Answer:
This can be done by a greedy solution. The algorithm does the following:
Put song 1 on CD1.
For song 1, if there's space left on the present CD, then put the song on the present CD. If not, use a replacement CD.
If there are not any CDs left, output "no solution".
Explanation:
The main thing is prove the correctness, do that by the "greedy stays ahead argument". For the primary song, the greedy solution is perfect trivially.
Now, let the optimal solution match the greedy solution upto song i. Then, if the present CD has space and optimal solution puts song (i+1) on an equivalent CD, then the greedy and optimal match, hence greedy is not any worse than the optimal.Else, optimal puts song (i + 1) on subsequent CD. Consider an answer during which only song (i + 1) is moved to the present CD and zip else is modified. Clearly this is often another valid solution and no worse than the optimal, hence greedy is not any worse than the optimal solution during this case either. This proves the correctness of the algorithm. As for every song, there are constantly many operations to try to do, the complexity is O(n).

You have a shared folder named Reports. Members of the Managers group have been given Write access to the shared folder. Mark Mangum is a member of the Managers group. He needs access to the files in the Reports folder, but he should not have any access to the Confidential.xls file. What should you do
Answer:
Following are the solution to the given question:
Explanation:
The common folder called Report has also been shared. Writing access to a shared folder was given to management group members. Mark is a member of a group of managers. We can access the files within your reporting directory, but you really should not access the Confidential.xls file. We want to add Mark Mangum to our ACL files using Deny permissions on Confidential.xls.

Would you prefer to use an integrated router, switch, and firewall configuration for a home network, or would you prefer to operate them as separate systems
Answer:
I would prefer to use an integrated router, switch, and firewall configuration for a home network instead of operating my home devices as separate systems.
Explanation:
Operating your home devices as separate systems does not offer the required good service in information sharing. To share the internet connection among the home devices, thereby making it cheaper for family members to access the internet with one Internet Service Provider (ISP) account rather than multiple accounts, a home network is required. A home network will always require a network firewall to protect the internal/private LAN from outside attack and to prevent important data from leaking out to the outside world.
Given an array of n distinct integers sorted in ascending order, write a function that returns a Fixed Point in the array, if there is any Fixed Point present in array, else returns -1. Fixed Point in an array is an index i such that arr[i] is equal to i. Note that integers in array can be negative. Examples: #include using namespace std; void removeDivByFive(int *arr,int& size) { int index=0; for(int i=0;i
Answer:
The function is as follows:
int returnsFixed(int arr [],int n){
int retVal = -1;
for(int i = 0; i<n;i++){
if(i == arr[i]){
retVal = i;
break;
}
}
return retVal;
}
Explanation:
This defines the functionl it receives the array and the length of the array
int returnsFixed(int arr [],int n){
This initializes the return value to -1
int retVal = -1;
This iterates through the array
for(int i = 0; i<n;i++){
This checks if i equals arr[i]
if(i == arr[i]){
If yes, the return value (i.e. the fixed point) is set to i
retVal = i;
And the code is exited
break;
} This ends the if condition
} This ends the iteration
This returns the calculated fixed point
return retVal;
}
write a loop that reads positive integers from stands input and that terinated when it reads an interger that is not positive after the loop termpinates
Loop takes only positive numbers and terminates once it encounters a negative numbers.
Answer and Explanation:
Using javascript:
Var positiveInt= window.prompt("insert positive integer");
While(positiveInt>=0){
Alert("a positive integer");
Var positiveInt= window.prompt("insert positive integer");
}
Or we use the do...while loop
Var positiveInt= window.prompt("insert positive integer");
do{
Var positiveInt= window.prompt("insert positive integer");
}
While (positiveInt>=0);
The above program in javascript checks to see if the input number is negative or positive using the while loop condition and keeps executing with each input until it gets a negative input

Which of the following restricts the ability for individuals to reveal information present in some part of the database?
a. Access Control
b. Inference Control
c. Flow Control
d. Encyption
Answer:
it would have to be flow control which would be C.
Explanation:
Flow Control is restricts the ability for individuals to reveal information present in some part of the database. Hence, option C is correct.
What is Flow Control?The management of data flow between computers, devices, or network nodes is known as flow control. This allows the data to be processed at an effective rate. Data overflow, which occurs when a device receives too much data before it can handle it, results in data loss or retransmission.
A design concern at the data link layer is flow control. It is a method that typically monitors the correct data flow from sender to recipient. It is very important because it allows the transmitter to convey data or information at a very quick rate, which allows the receiver to receive it and process it.
The amount of data transmitted to the receiver side without any acknowledgement is dealt with by flow control.
Thus, option C is correct.

A recursive method may call other methods, including calling itself. A recursive method has:
1. a base case -- a case that returns a value or exits from a method without performing a recursive call.
2. a recursive case -- calling the method again with a smaller case..
Study the recursive method given below.
For example, this call recursiveMethod (5); returns 15:
public static int recursiveMethod (int num) (
if (num == 0)
return 1;
else {
if (numX2!=0)
return num * recursiveMethod (num -1);
else
return recursiveMethod (num-1);
}
}
1 What is the base case?
2. What does the following statement check?
3. What does the method do?
Answer:
Hence the answer is given as follows,
Explanation:
Base Case:-
If (num == 0) //This is the base case for the given recursive method
return 1;
If(num % 2!=0) checks whether num is odd.
The above condition is true for all odd numbers and false for even numbers.
if the remainder is not equal to zero when we divide the number with 2 then it is odd.
The method:-
The above recursive method calculates the product of odd numbers up to the given range(that is num)
For num=5 => 15(5*3*1).
For num=7 => 105(7*5*3*1).
For num=10 => 945(9*7*5*3*1).
