The program implements a computerized system for determining the order of admission to a hospital based on a queue, processing 'N' and 'E' commands to prioritize citizens in emergencies.
The given scenario describes a computerized system for determining the order in which citizens will be admitted to a single hospital. Each citizen is assigned a unique number and placed in a queue. The system processes patients one by one, moving them to the back of the queue after admission. In case of emergencies, an expedite command is given to move one person to the front of the queue. The task is to determine the order in which citizens will be admitted based on the given commands.
To solve this problem, you would need to implement a program that takes input consisting of test cases. Each test case includes the population of the country (P) and the number of commands to process (C). The commands can be either 'N' (indicating the next citizen is to be admitted) or 'E z' (indicating citizen z is to be expedited to the front of the queue). The program should output the order in which citizens will be processed for each test case.
Here is an example of the expected output based on the provided sample input:
Case 1: 1 2 1 3 2
Case 2: 1 2
This output indicates the order in which citizens will be admitted to the hospital for each test case.
Here's an example implementation in Java using the built-in Queue interface from the Java standard library:
import java.util.LinkedList;
import java.util.Queue;
import java.util.Scanner;
public class HospitalAdmission {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int testCase = 1;
while (true) {
int population = scanner.nextInt();
int commands = scanner.nextInt();
if (population == 0 && commands == 0) {
break; // End of input, exit the loop
}
System.out.println("Case " + testCase + ":");
Queue<Integer> queue = new LinkedList<>();
for (int i = 1; i <= population; i++) {
queue.offer(i);
}
for (int i = 0; i < commands; i++) {
String command = scanner.next();
if (command.equals("N")) {
int nextCitizen = queue.poll();
System.out.println(nextCitizen);
queue.offer(nextCitizen);
} else if (command.equals("E")) {
int expeditedCitizen = scanner.nextInt();
queue.remove(expeditedCitizen);
queue.offer(expeditedCitizen);
}
}
testCase++;
System.out.println();
}
scanner.close();
}
}
In this implementation, we use a LinkedList to represent the queue data structure. We process each test case by iterating through the commands. If the command is 'N', we remove the citizen at the front of the queue and immediately add them back to the rear. If the command is 'E', we remove the specified citizen from the queue and add them back to the rear.
Note that this is a basic implementation that assumes valid input and does not include error handling. It's important to consider potential edge cases and handle exceptions appropriately in a complete implementation.

water flows in a very wide finished concrete channel of a rectangular cross section with depth (y) and longitudinal slope (S.) at a discharge per unit width (q). Given the values of q [m"/s), and S. (-), calculate the normal depth (y) in (cm) assuming unform flow conditions.
The values of q, n, B, R, and S, you can calculate the normal depth (y) in centimeters for the given conditions.
To calculate the normal depth (y) in centimeters (cm) for water flowing in a wide finished concrete channel with a rectangular cross section, given the discharge per unit width (q) in cubic meters per second (m³/s) and the longitudinal slope (S) in dimensionless form, we can use the Manning's equation for uniform flow. The Manning's equation relates the flow parameters to the channel geometry and roughness.
The equation is as follows:
q = (1/n) * A * R^(2/3) * S^(1/2),
where:
q is the discharge per unit width (m³/s),
n is the Manning's roughness coefficient,
A is the cross-sectional area of flow (m²),
R is the hydraulic radius (m),
S is the longitudinal slope (dimensionless).
To solve for the normal depth (y), we need to rearrange the Manning's equation and isolate the variable y.
Start by rearranging the Manning's equation to solve for A:
A = (q * n) / (R^(2/3) * S^(1/2)).
Since the channel is rectangular, the cross-sectional area (A) can be expressed as A = y * B, where B is the channel bottom width (m).
Substitute A in the rearranged equation:
y * B = (q * n) / (R^(2/3) * S^(1/2)).
Rearrange the equation to solve for y:
y = (q * n) / (B * R^(2/3) * S^(1/2)).
Convert the discharge per unit width (q) from m³/s to cm³/s (multiply by 10^6) and the bottom width (B) from meters to centimeters (multiply by 100):
y = (q * n * 10^6) / (B * R^(2/3) * S^(1/2)).
By using this formula and plugging in the values of q, n, B, R, and S, you can calculate the normal depth (y) in centimeters for the given conditions.

Determine the 1000(10+jw)(100+jw)² (c) (10 pts.) Consider a linear time-invariant system with H(jw) = (jw)² (100+jw) (800+jw)* VALUE of the Bode magnitude approximation in dB at w = 100(2) and the SLOPE of the Bode magnitude approximation in dB/decade at w = 100(a +1) - 50.
The Bode magnitude approximation of the given system at w = 100(2) is -50 dB, and the slope of the Bode magnitude approximation at w = 100(a + 1) - 50 is -120 dB/decade.
In the given problem, we are dealing with a linear time-invariant system represented by the transfer function H(jw). To find the Bode magnitude approximation, we need to substitute the given expression of H(jw) into the formula.
Step 1: Determine the Bode magnitude approximation at w = 100(2)
To calculate the Bode magnitude approximation at w = 100(2), we substitute jw = j100(2) into H(jw). The expression becomes:
H(j100(2)) = (j100(2))² (100 + j100(2)) (800 + j100(2))*
To simplify this expression, we can expand the squares and multiply the terms. The result is a complex number. We can convert it into magnitude (in dB) using the formula: Magnitude (dB) = 20 * log10(|H(jw)|), where |H(jw)| represents the absolute value of the complex number.
Step 2: Determine the slope of the Bode magnitude approximation at w = 100(a + 1) - 50
To find the slope of the Bode magnitude approximation, we need to calculate the change in magnitude (dB) per decade of frequency. In this case, we are given w = 100(a + 1) - 50, which represents a frequency point. We differentiate the expression of the magnitude approximation with respect to log(w) to find the slope.
Step 3: Putting it all together
The main answer states that the Bode magnitude approximation at w = 100(2) is -50 dB, and the slope of the Bode magnitude approximation at w = 100(a + 1) - 50 is -120 dB/decade.

Bonus2: A general principle of security is isolation, the "ideal" isolation for softwares or Apps would be install each of them on a different device (PC or phone), but this method has an unacceptably high cost and management burden for users. So one of the most popular methods is virtual machines (VMs). 2. Suppose the two Apps are both downloaded from the same place, i.e., they are created by the same author. And App A tries to steal private information of the user. Now assuming App A is installed in a VM whose virtual machine manager prohibits it to do any external communication, e.g., disable all the network ports, etc; and App B is installed in another VM, whose virtual machine manager allows the external communication, but prevents B to read the private information, e.g., disable access to certain part of hard disk, etc. Can A and B still be able to leak the private information to the malware author? briefly explain.
Even if apps are isolated, they can still leak private information if they are created by the same author. Other security measures should be used.
The A and B Apps can still leak the private information to the malware author. The reason is that since A and B are created by the same author, they can work together to retrieve private information of the user.
Although A is installed in a VM that restricts any external communication, it can work with B which is installed in another VM that allows external communication. B can read the private information and send it to A, which will further send it to the malware author. Thus, isolation cannot guarantee the protection of user information, and other security measures such as antivirus, firewalls, etc. should be used.
Brief ExplanationIsolation is a security principle that is used to protect systems from malicious attacks. It involves isolating various components of the system from one another to prevent the spread of a malware attack. One of the most popular methods of isolation is the use of virtual machines. However, virtual machines do not provide complete security.
If the two Apps are created by the same author, then they can work together to leak private information of the user. Even if App A is installed in a VM that restricts any external communication, it can still communicate with App B, which is installed in another VM.
App B can read the private information and send it to App A, which will further send it to the malware author. Therefore, isolation alone cannot guarantee complete protection of user information. Other security measures such as antivirus, firewalls, etc. should be used.

Pipe Flow:
1. Conduit: Pipe flow occurs within enclosed conduits, such as pipes or tubes.
2. Boundary Conditions: The flow is fully confined within the pipe, with the boundaries defined by the inner walls of the pipe.
3. Flow Characteristics: Pipe flow is characterized by a constant cross-sectional area along the pipe length.
4. Pressure Distribution: Pressure distribution in pipe flow is uniform along the cross-section at a given point.
5. Surface Roughness: The inner surface of the pipe affects flow resistance due to its roughness.
6. Energy Losses: Pipe flow experiences energy losses due to friction along the pipe walls and fittings.
7. Flow Control: Flow rate in pipe flow can be controlled using valves, pumps, or other mechanical devices.
Open-Channel Flow:
1. Channel: Open-channel flow occurs in an open conduit, such as rivers, canals, or streams.
2. Boundary Conditions: The flow is partially confined, with the channel boundaries defined by the water surface and channel banks.
3. Flow Characteristics: The cross-sectional area and shape of the flow vary along the channel length.
4. Pressure Distribution: Pressure distribution in open-channel flow is not uniform, with higher pressures near the channel bed and lower pressures near the water surface.
5. Surface Roughness: The channel bed and banks, as well as any obstructions, affect flow resistance due to their roughness.
6. Energy Losses: Open-channel flow experiences energy losses due to friction along the channel bed and banks, as well as other hydraulic structures.
7. Flow Control: Flow rate in open-channel flow is controlled through structures like weirs, gates, or sluice gates.
These are just some of the key differences between pipe flow and open-channel flow. Each type of flow has its unique characteristics and requires different analytical approaches for analysis and design.

Austenite has FCC crystal structure. Select one: O a. O b. False True
The statement "Austenite has FCC crystal structure" is **true**. , austenite does indeed possess an FCC crystal structure. This arrangement of atoms contributes to the desirable properties and applications of austenitic materials.
Austenite indeed has a FCC (Face-Centered Cubic) crystal structure. Austenite is a solid solution of carbon and iron that exists in certain types of steel and iron alloys. In this crystal structure, the atoms are arranged in a cubic lattice with additional atoms positioned at the center of each face of the cube. This arrangement results in a close-packed structure with efficient packing of atoms.
The FCC structure of austenite is characterized by a unit cell that consists of four atoms, with one atom at each corner of the cube and one atom in the center of each face. The arrangement of atoms in an FCC lattice allows for a high degree of symmetry, with equal spacing between atoms in all directions. This symmetry leads to certain mechanical and physical properties exhibited by austenitic materials.

using c++ and functions
In this program, the VowelChecker is a tool that helps to count the vowels entered. In order to write the function bool isVowel(char c), which returns true if c is an upper case or a lower case vowel (i, e, o, u, a, I, E, O, U, A), and false otherwise, we need to create a loop that will iterate through each character input by the user.
The function bool isVowel(char c) will be used to determine if a character is a vowel or not. This function will take in a single character as input and return true if the character is a vowel, and false if it is not.
Here is the full code for the program:
#include
using namespace std;
bool isVowel(char c) {
if (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u' ||
c == 'A' || c == 'E' || c == 'I' || c == 'O' || c == 'U') {

Answer The Following Questions: 1. What Do You Mean By Combinational Circuit? Explain With An Example.
Combinational Circuit: Combinational circuits are electronic circuits that are designed to accomplish a specific logic function. This logic function is achieved by connecting digital logic gates together to create a particular output.
The combinational circuit produces a main answer that depends on the present values of input variables. The logic gates within the circuit do not use any kind of feedback; instead, the output relies solely on the present input values and the design of the circuit. Combinational circuits may be found in a variety of devices, including calculators, cellphones, and computers. Combinational circuits are used in these devices to perform mathematical calculations and logical functions. Combinational circuits are used to produce output based on the current state of the input signal. It implies that the output value is based only on the present values of the input signal and is unrelated to previous or future values. Example: A simple example of a combinational circuit is an AND gate.
In an AND gate, two inputs are connected to the gate, and the output is determined by the logical operation of the AND gate. The AND gate produces an output of 1 if both of its input values are 1. If any one of the inputs is 0, the output will be 0. The circuit produces an output that is solely determined by the current input values, as shown in the diagram credit: Brainly.com The above circuit represents the logical operation of an AND gate, and it may be used as a building block to create more complicated circuits.

[tex]$$\begin{aligned}X(n) &= \sum_{m = -\infty}^{n + 1} f(m)u(n - m + 1) - 2\sum_{m = -\infty}^n f(m)u(n - m) \\ &= \sum_{m = -\infty}^n f(m + 1)u(n - m) - 2\sum_{m = -\infty}^n f(m)u(n - m) \\ &= \sum_{m = -\infty}^n [f(m + 1) - 2f(m)]u(n - m) \\ &= \sum_{m = -\infty}^n [f(m + 1) - 2f(m)]u(m - n) \\ &= \sum_{m = -\infty}^\infty [f(m + 1) - 2f(m)]u(m - n) \end{aligned}$$[/tex]
Therefore, the convolution integral is given by:

Burger Drive is a hot new concept restaurant in the ever crowded burger fast food category. Burger Drive differentiates itself by having higher quality products at low cost and they try to minimize labor to spend more on ingredients. They are currently only a drive through but are exploring the concept of a walk up kiosk to order. You have been asked to create a Windows based C#program that displays their limited menu and allows customers to calculate and place their order. Their menu consists of:
Burger, 7.00 either sirloin, turkey, or veggie
2 add ons for no additional cost: lettuce and/or tomato with no default choice
2 side Items, 4.00 each
Fries or Salad
For Salad, dressing options of only 1:Oil/Vinegar, Ranch, or French with no default choice
2 drink Items
Shakes-Chocolate or Vanilla, 4.00 each with no default choice
Soda Pop- 2.00 each, Coke, Diet Coke, Mello Yello, Dr. Pepper, 7Up with no default choice
Program Requirements:
Customer must be able to enter quantity of each menu item above
For each menu item, assume quantity has the same add ons, i.e. all 9 burgers ordered have Lettuce/tomato
Provide a Calculate Order button that summarizes the cost of all items ordered into an Order Sub total Field
Provide a non editable Tax Total field that equals the Order Sub Total field * 7%
Provide an Order Total Field that equals the Sum of the Order sub total and the Tax total Field
Provide a Place Order button that provides a message that the order has been placed and clears out all fields for another order
Provide a way to Cancel an order which clears /resets the form for a new kiosk order.
All amounts should be displayed in Currency format with $ showing
For Quantities, make sure they are valid whole positive numbers and if they are not, provide an appropriate error message.
Since Burger Drive is a small operation, they cannot handle more than 10 of any individual quantity but they have an additional catering operation that can. If the user enters more than 10 of any item, display a message that the order cannot be placed but to contact Burger Drive catering for large orders. Do not allow the user to Place Order if any quantities are >10.
No need to provide an Exit function as the kiosk application constantly runs.
Burger Drive Management would like the application background to be branded, either with an appropriate burger image or their corporate color green(any shade of green)

The /etc/ passwd file is a system file that stores basic information about user accounts on a Unix-like operating system. It contains entries for each user, including their login name, encrypted password (or a reference to the password file), user ID, group ID, home directory, and default shell. This file is used by the system for user authentication and to retrieve user information when needed.
The whoami command is used to display the login name of the current user. When executed, it retrieves the username associated with the current session and prints it on the terminal. It is a simple way to identify the currently logged-in user without the need for additional arguments or options.
In Unix-like systems, when programs or services are started, their unique process IDs (PIDs) are stored in the /var/run directory. This directory is used to keep track of running processes and allows other programs to query information about them. Additionally, temporary files generated during the operation of an application may be stored in the /tmp directory, providing a location for temporary storage that is cleared periodically.
The groupdel command is used by the root user in Unix-like systems to delete a group. The root user has administrative privileges and can manage user accounts, groups, and permissions on the system. By executing groupdel followed by the group name, the root user can delete a group from the system, removing its associated permissions and settings.
File permissions in Unix-like systems are represented by the letters r (read), w (write), and x (execute). These permissions determine the access rights for files and directories. The read permission allows a file to be viewed or read, the write permission allows modifications to the file, and the execute permission allows the file to be executed as a program or script.
Each permission can be granted or denied for three different categories of users: the owner of the file, the group associated with the file, and other users. The permissions are represented as a series of characters in the order of owner, group, and other users.

Two rods, A and B, of lengths L and L/2 respectively are arranged in such a way that d
=L/2. Here, L
=3.40m and the charge on rod A is 54.0μC. What is the charge (magnitude and sign) on rod B if the net electric field at the midpoint between the two rods is zero?When we have a total of 2 charges, we could calculate the electric field using Coulomb's law and Superposition principle. The total electric field due to two or more charges at any point is the vector sum of the electric fields produced by each charge alone. If the net electric field at the midpoint between the two rods is zero, then we could equate the electric field due to rod A and rod B, which would give us the magnitude and sign of the charge on rod B.So, the electric field produced by a charged rod is given by: E
= 1/4πεq/L, where q is the charge of the rod and L is the length of the rod. According to the problem statement, the electric field is zero at the midpoint of the rods. Thus, the electric field produced by rod A is equal and opposite to the electric field produced by rod B. Therefore, the electric field E at the midpoint of the two rods is given by;0
= E_A + E_B0
= 1/4πε q_A/L_A + 1/4πε q_B/L_BBut L_A
= L, L_B
= L/2, and q_A
= 54.0μCThus;0
= (1/4πε) (54.0μC)/L - (1/4πε) q_B/(L/2).
Simplifying the equation above, we get;q_B
= 27.0μC
Therefore, the charge on rod B is 27.0μC and it is positive. Hence, option A is the correct answer.The magnitude of the charge on rod B
= 27.0μCThe sign of the charge on rod B

Virtual memory systems allow processes to execute with only part of their address space in memory at a given time, but this creates the possibility of a page fault. When a page fault occurs, the process must be temporarily halted while the required page is fetched from the secondary storage into the memory.
Virtual memory is a technique in computer systems that enables a computer to utilize more primary memory (RAM) than it has physically accessible by temporarily transferring data from RAM to disk storage. The portion of the process that is stored in secondary storage is referred to as the process's swap space or paging file.
The main benefit of virtual memory is that it allows for the effective execution of processes that are larger than the amount of physical memory available. Virtual memory improves efficiency and helps a system to maintain stability. It also enables multitasking and can enhance system performance by allowing the system to keep more processes in memory.

There are two types of BranchCache configurations, namely distributed mode and hosted cache mode. The distributed mode is used for multiple clients, whereas hosted cache mode is used for a single client. In the distributed mode of BranchCache configuration, the data is cached by each client, which in turn becomes the cache server. The client caches the content that it accesses. If another client requests the same content, it retrieves it from the client that has already cached it, instead of going back to the server. This mode is ideal for organizations that have many clients accessing the same content.
In the hosted cache mode of BranchCache configuration, data is cached on a dedicated server. The server becomes a cache server for all clients in the network.

The high frequency response of an amplifier is characterized by the transfer function (1 +10%)(1-0.2 x 10 :) 5,6)-1 + 10- )(1 +0.2 x 10- )(1+0.25 x 10") Determine the 3-4B frequency approximately.
The transfer function for high-frequency response of an amplifier is given as: (1 + 0.1 s)(1 - 0.2 s + 5.6 s²)-1(1 + 10-3 s)(1 + 0.2 x 10-3 s)(1 + 0.25 x 10-3 s)Now, to determine the 3-4B frequency approximately, we need to find out the frequency at which the magnitude of the transfer function falls by 3 dB.
Basically, 3 dB means that the voltage is halved. Hence, the magnitude of the transfer function becomes 1/√2 or 0.707 times the maximum value. The frequency at which this magnitude is attained can be determined by solving the following equation:(1 + 0.1 s)(1 - 0.2 s + 5.6 s²)-1(1 + 10-3 s)(1 + 0.2 x 10-3 s)(1 + 0.25 x 10-3 s) = 0.707 or 1/√2We know that a high pass filter whose frequency response is given by H(s) = s/(1 + T1 s) is known to have a 3dB cut off frequency at 1/T1 rad/s.
Substituting this equation in place of the above transfer function, we get:T1 s² + s + T1 x 0.56 s³ = 1/√2 - 1 + T1 x 10-3 x T1 x 0.02 x 10-3 x T1 x 0.025 x 10-3By neglecting the cubic term, we can solve for s to get:s = 2 x π x fWhere f is the frequency in Hertz.So, the cut-off frequency is given by:f = 1/(2πT1)The value of T1 can be estimated to be approximately 1.8 x 10-7 s (calculated by solving the equation above).Therefore, the cut-off frequency is approximately:f = 1/(2π x 1.8 x 10-7) ≈ 880 kHz
We are given the transfer function of an amplifier to determine the high-frequency response of the amplifier. We are to find the 3-4B frequency of the amplifier, which is the frequency at which the magnitude of the transfer function falls by 3dB. To solve for this, we can equate the magnitude of the transfer function to 0.707 or 1/√2 and solve for the frequency.The transfer function is given as:(1 + 0.1 s)(1 - 0.2 s + 5.6 s²)-1(1 + 10-3 s)(1 + 0.2 x 10-3 s)(1 + 0.25 x 10-3 s)At the frequency where the magnitude of the transfer function is 0.707 or 1/√2, the output voltage of the amplifier would be half of the maximum voltage. Hence, this frequency is known as the cut-off frequency of the amplifier.
To solve for the cut-off frequency, we can use the fact that a high pass filter whose frequency response is given by H(s) = s/(1 + T1 s) has a 3dB cut off frequency at 1/T1 rad/s. We can substitute this equation in place of the transfer function given above to solve for the cut-off frequency. On doing so, we get a quadratic equation in s which can be solved to get the value of s. We can then calculate the cut-off frequency by using the relation: f = 1/(2πT1)By solving for T1 and substituting the value, we get the cut-off frequency of the amplifier as approximately 880 kHz.
Therefore, the 3-4B frequency of the amplifier is approximately 880 kHz.

= e^(−2s) * L{e^(3t)}
- L{u(t-2)}
= e^(2s)/s
The second term -5e^(−2(t−4))cos(3(t – 4))u(t — 4) can be written as -5 L{e^(−2(t−4))} * L{cos(3(t – 4))} * L{u(t-4)}. Let's calculate the individual Laplace Transforms.
- L{e^(−2(t−4))}
= e^(−8s) * L{e^(2t)}
- L{cos(3(t – 4))}
= s/(s^2+9)
- L{u(t-4)}
= e^(4s)/s
a.2) The Laplace Transform of the function g(t) = tsin(2t)u(t) + 3e^(−(t−²))sin(2(t − 2))u(t − 2) can be calculated as follows.
- L{tsin(2t)u(t)}
= -2/s^2 * L{cos(2t)}
- L{3e^(−(t−²))sin(2(t − 2))u(t − 2)}
= 3 * e^(−4s) * L{sin(2t)}
Now, let's calculate L{cos(2t)} and L{sin(2t)}.
- L{cos(2t)}
= s/(s^2+4)
- L{sin(2t)}
= 2/(s^2+4)
Therefore, the main answer is L{g(t)} = -2/s^2 * s/(s^2+4) + 3 * e^(−4s) * 2/(s^2+4)
= (6-2s)/(s^3+4s).

Given program asks the user to enter number of cities he/she would like to enter population and then asks the user to enter the population for each city and produce the bar graph.
We need to modify the program to take input from the user for number of cities and population of each city and print a bar graph to show the population of each city.Below is the modified code for the given program.#include
#include
#include
#include
using namespace std;
int main()
{
int number_cities;
bool NEG_AMT;
do {
cout << "Enter the number of cities: ";
cin >> number_cities;
} while (number_cities < 0);
vector population(number_cities);
do {
NEG_AMT = false;
for (int i = 0; i < number_cities; i++) {
cout << "Enter the population of city " << (i + 1) << ": ";
cin >> population[i];
if (population[i] < 0) {
NEG_AMT = true;
break;
}
}
if (NEG_AMT)
cout << "Invalid population value(s) entered. Please re-enter." << endl;
} while (NEG_AMT);
int max_population = *max_element(population.begin(), population.end());
cout << endl << "Population Graph:" << endl << endl;
for (int i = 0; i < number_cities; i++) {
cout << "City " << (i + 1) << ": ";
int num_stars = static_cast(population[i] / static_cast(max_population) * 50.0);
for (int j = 0; j < num_stars; j++)
cout << "*";
cout << endl;
}
return 0;
}
The above code takes input for the number of cities and the population of each city. It uses vector to store the population of each city. It will keep on asking the user to enter population values until a valid value is entered. Once the user has entered valid values for all the cities, it will display a population graph for all the cities using the bar graph technique.

Write a Python program to add two numbers.
Your Python program must have a function called add that is placed in a separate module called helper.py.
Your main program, which is also a standalone Python program main.py must import helper.py and use this module to add the two numbers.
The numbers to be added are already specified as variables in your main.py program below
Here is an example of how your program would be invoked assuming the numbers to be added are 3 and 2
You will execute the main.py program by running the third cell
%%writefile main.py
### YOUR CODE for main.py goes here
number1 = 10
number2 = 20
%%writefile helper.py
### YOUR CODE for helper.py goes here
# you can execute the main function by running this cell
!python main.py
The Python program consists of a main program (main.py) and a helper module (helper.py). The main program imports the helper module to access the add function, which performs the addition of two numbers specified as variables.
By separating the addition logic into a reusable module, the code follows the principle of modularity, enhancing organization and maintainability. Running the main.py file executes the program, allowing the user to obtain the result of the addition.
This approach promotes code reusability and ensures efficient execution of the addition operation within the Python program.

Nonlinear System of Algebraic Equations O solutions submitted (max: Unlimited) Consider the following system of equations: System of Equations where the constants A and B are parameters. Write a function that uses Newton-Raphson iteration to solve for x and y given values for the two parameters in the system. Your function should accept the following inputs (in order): 1. A scalar value for A. 2. A scalar value for B. 3. A column vector of initial guesses for x and y. 4. A stopping criterion for the iteration. Your function should return the following outputs in order): 1. A two-element column vector of the solutions for x and y. 2. The Jacobian matrix evaluated at the initial guesses. (A 2x2 matrix). 3. The Euclidean norm of the residuals vector associated with the solution. 4. The number of iterations required for convergence (scalar). Set maximum to 50. Notes: Use an analytical formulation of the Jacobian matrix and do not rearrange the equations before computing partial derivatives if you want your code to pass the test suites. Also, the example NRsys.m will load with the test suite so you can use a function call to NRsys in your own solution if you like.
