In this puzzle you have a list of n pitchers, with known capacities, c1, c2, ... cn, of holding water in gallons. You have a faucet that can be used as often and as much as the player needs. The goal is to measure exactly g gallons of water, using nothing other than these pitchers. Suppose the current amounts of water that these pitchers hold is w1, w2, ... wn,. These numbers are assumed to be 0 initially. The puzzle is solved as soon as wi = g for any i. A player can perform the following operations:

 Fill pitcher i (from the faucet). The precondition of this operation is: ci > wi ≥ 0. The effect is: wi = ci.

 Empty pitcher i. The precondition of this operation is: ci ≥ wi > 0. The effect is: wi = 0.

 Pour pitcher i to pitcher j. The precondition of this operation is: (ci ≥ wi > 0) and (cj > wj ≥ 0). In words, pitcher i must have some water to pour, and pitcher j must have some unused capacity to receive it. The (partial) effect is: (wi = 0) or (wj = cj) or both. In words, the pour operation must continue until pitcher i becomes empty (and its content is added to pitcher j's content), or pitcher j becomes full (and pitcher i retains the remainder), whichever occurs first. They may occur simultaneously.

5.14 ◆ Write a version of the inner product procedure described in Problem 5.13 that uses 6 × 1 loop unrolling. For x86-64, our measurements of the unrolled version give a CPE of 1.07 for integer data but still 3.01 for both floating-point data. A. Explain why any (scalar) version of an inner product procedure running on an Intel Core i7 Haswell processor cannot achieve a CPE less than 1.00. B. Explain why the performance for floating-point data did not improve with loop unrolling.

Answers

Answer:

(a) the number of times the value is performs is up to four cycles. and as such the integer i is executed up to 5 times.  (b)The point version of the floating point can have CPE of 3.00, even when the multiplication operation required is either 4 or 5 clock.

Explanation:

Solution

The two floating point versions can have CPEs of 3.00, even though the multiplication operation demands either 4 or 5 clock cycles by the latency suggests the total number of clock cycles needed to work the actual operation, while issues time to specify the minimum number of cycles between operations.

Now,

sum = sum + udata[i] * vdata[i]

in this case, the value of i performs from 0 to 3.

Thus,

The value of sum is denoted as,

sum = ((((sum + udata[0] * vdata[0])+(udata[1] * vdata[1]))+( udata[2] * vdata[2]))+(udata[3] * vdata[3]))

Thus,

(A)The number of times the value is executed is up to 4 cycle. And the integer i performed up to 5 times.

Thus,

(B) The floating point version can have CPE of 3.00, even though the multiplication operation required either 4 or 5 clock.

Answers

Answer:

A. 0.0450

B. 4

C. 0.25

D. 37.68

E. 6Hz

F. -0.523

G. 1.5m/s

H. vy = ∂y/∂t = 0.045(-37.68) cos (25.12x - 37.68t - 0.523)

I. -1.67m/s.

Explanation:

Given the equation:

y(x,t) = 0.0450 sin(25.12x - 37.68t-0.523)

Standard wave equation:

y(x, t)=Asin(kx−ωt+ϕ)

a.) Amplitude = 0.0450

b.) Wave number = 1/ λ

λ=2π/k

From the equation k = 25.12

Wavelength(λ ) = 2π/25.12 = 0.25

Wave number (1/0.25) = 4

c.) Wavelength(λ ) = 2π/25.12 = 0.25

d.) Angular frequency(ω)

ωt = 37.68t

ω = 37.68

E.) Frequency (f)

ω = 2πf

f = ω/2π

f = 37.68/6.28

f = 6Hz

f.) Phase angle(ϕ) = -0.523

g.) Wave propagation speed :

ω/k=37.68/25.12=1.5m/s

h.) vy = ∂y/∂t = 0.045(-37.68) cos (25.12x - 37.68t - 0.523)

(i) vy(3.5m, 21s) = 0.045(-37.68) cos (25.12*3.5-37.68*21-0.523) = -1.67m/s.

Implement the function pairSum that takes as parameters a list of distinct integers and a target value n and prints the indices of all pairs of values in the list that sum up to n. If there are no pairs that sum up to n, the function should not print anything. Note that the function does not duplicate pairs of indices

Answers

Answer:

Following are the code to this question:

def pairSum(a,x): #find size of list

   s=len(a) # use length function to calculte length of list and store in s variable

   for x1 in range(0, s):  #outer loop to count all list value

       for x2 in range(x1+1, s):    #inner loop

           if a[x1] + a[x2] == x:    #condition check

               print(x1," ",x2) #print value of loop x1 and x2  

pairSum([12,7,8,6,1,13],13) #calling pairSum method

Output:

0   4

1   3

Explanation:

Description of the above python can be described as follows:

In the above code, a method pairSum is declared, which accepts two-parameter, which is "a and x". Inside the method "s" variable is declared that uses the "len" method, which stores the length of "a" in the "s" variable. In the next line, two for loop is declared, in the first loop, it counts all variable position, inside the loop another loop is used that calculates the next value and inside a condition is defined, that matches list and x variable value. if the condition is true it will print loop value.

Write a program that has an input as a test score, and figures out a letter grade for that score, such as "A", "B", "C", etc. according to the scale: 90 or more - A 80 - 90 (excluding 90) - B 70 - 80 (excluding 80) - C 60 - 70 (excluding 70) - D else - F The program should print both a test score, and a corresponding letter grade. Test your program with different scores. Use a compound IF-ELSE IF statement to find a letter grade.

Answers

Answer:

The program in csharp for the given scenario is shown.

using System;

class ScoreGrade {

static void Main() {

//variables to store score and corresponding grade

double score;

char grade;

//user input taken for score

Console.Write("Enter the score: ");

score = Convert.ToInt32(Console.ReadLine());

//grade decided based on score

if(score>=90)

grade='A';

else if(score>=80 && score<90)

grade='B';

else if(score>=70 && score<80)

grade='C';

else if(score>=60 && score<70)

grade='D';

else

grade='F';

//score and grade displayed  

Console.WriteLine("Score: "+score+ " Grade: "+grade);

}

}

OUTPUT1

Enter the score: 76

Score: 76 Grade: C

OUTPUT2

Enter the score: 56

Score: 56 Grade: F

Explanation:

1. The variables to hold the score and grade are declared as double and char respectively.

int score;

char grade;

2. The user is prompted to enter the score. The user input is not validated and the input is stored in the variable, score.

3. Using if-else-if statements, the grade is decided based on the value of the score.

if(score>=90)

grade='A';

else if(score>=80 && score<90)

grade='B';

else if(score>=70 && score<80)

grade='C';

else if(score>=60 && score<70)

grade='D';

else

grade='F';

4. The score and the corresponding grade are displayed.

5. The program can be tested for different values of score.

6. The output for two different scores and two grades is included.

7. The program is saved using ScoreGrade.cs. The .cs extension indicates a csharp program.

8. The whole code is written inside a class since csharp is a purely object-oriented language.

9. In csharp, user input is taken using Console.ReadLine() which reads a string.

10. This string is converted into an integer using Convert.ToInt32() method.

score = Convert.ToInt32(Console.ReadLine());

11. The output is displayed using Console.WriteLine() or Console.Write() methods; the first method inserts a line after displaying the message which is not done in the second method.

12. Since the variables are declared inside Main(), they are not declared static.

13. If the variables are declared outside Main() and at the class level, it is mandatory to declare them with keyword, static.

Design and implement the Heap.h header using the given Heap class below:
template
class Heap
public:

T remove() throw (runtime_error);
// Insert element into the heap and maintain the heap property
void add(const T& element);
// Get the number of element in the heap
int getSize() const;

vector v;
Removing the root in a heap - after the root is removed, the tree must be rebuilt to maintain the heap property:
Move the last node to replace the root;
Let the root be the current node;
While (the current node has children and the current node is smaller than one of its children) Swap the current node with the larger of its children; The current node now is one level down;}
Adding a new node - to add a new node to the heap, first add it to the end of the heap and then rebuild the tree as follows:
Let the last node be the current node;
While (the current node is greater than its parent)
{Swap the current node with its parent; The current node now is one level up:}
To test the header file, write the heapSort function and use the following main program:
#include
#include "Heap.h"
using namespace std;
template
void heapSort(T list[], int arraySize) 1/
your code here .. p

Components of a product or system must be
1) Reliable
2) Flexible
3) Purposeful
4)Interchangeable

Answers

Answer:

The correct answer to the following question will be Option D (Interchangeable).

Explanation:

Interchangeability applies towards any portion, part as well as a unit that could be accompanied either by equivalent portion, component, and unit within a specified commodity or piece of technology or equipment.This would be the degree to which another object can be quickly replaced with such an equivalent object without re-calibration being required.

The other three solutions are not situation-ally appropriate, so option D seems to be the right choice.

Write the definition of a function words_typed, that receives two parameters. The first is a person's typing speed in words per minute (an integer greater than or equal to zero). The second is a time interval in seconds (an integer greater than zero). The function returns the number of words (an integer) that a person with that typing speed would type in that time interval.

Answers

Answer:

   //Method definition of words_typed

   //The return type is int

   //Takes two int parameters: typingSpeed and timeInterval

   public static int words_typed(int typingSpeed, int timeInterval) {

       //Get the number of words typed by  

       //finding the product of the typing speed and the time interval

       //and then dividing the result by 60 (since the typing speed is in "words

       // per minute"  and the time interval is in "seconds")

       int numberOfWords = typingSpeed * timeInterval / 60;

       

       //return the number of words

       return numberOfWords;

       

   }        //end of method declaration

Explanation:

The code above has been written in Java and it contains comments explaining each of the lines of the code. Please go through the comments.

Answer:

I am writing the program in Python.

def words_typed(typing_speed,time_interval):

   typing_speed>=0

   time_interval>0

   no_of_words=int(typing_speed*(time_interval/60))

   return no_of_words

   

output=words_typed(20,30)

print(output)

Explanation:

I will explain the code line by line.

First the statement def words_typed(typing_speed,time_interval) is the definition of a function named words_typed which has two parameters typing_speed and time_interval.

typing_speed variable of integer type in words per minute.

time_interval variable of int type in seconds

The statements typing_speed>=0 and time_interval>0 means that value of typing_speed is greater than or equal to zero and value of time_interval is greater than zero as specified in the question.

The function words_typed is used to return the number of words that a  person with typing speed would type in that time interval. In order to compute the words_typed, the following formula is used:

   no_of_words=int(typing_speed*(time_interval/60))

The value of typing_speed is multiplied by value of time_interval in order to computer number of words and the result of the multiplication is stored in no_of_words. Here the time_interval is divided by 60 because the value of time_interval is in seconds while the value of typing_speed is in minutes. So to convert seconds into minutes the value of time_interval is divided by 60 because 1 minute = 60 seconds.

return no_of_words statement returns the number of words.

output=words_typed(20,30) statement calls the words_typed function and passed two values i.e 20 for typing_speed and 30 for time_interval.

print(output) statement displays the number of words a person with typing speed would type in that time interval, on the output screen.

Fill in the blanks to make the factorial function return the factorial of n. Then, print the first 10 factorials (from 0 to 9) with the corresponding number.

In the question the information is missing the code is missing which we have to correct it following are the code that are mention below.

def factorial(n): # function

   result=1 #variable

   for x in range(       ): #iterating the loop

       result=  #storing result

   return  #return result

for n in range(  ): #iterating loop

   print(n,factorial(n)) #print factorial

Following are the description of code

We have create a function factorial  in this we have pass the one parameter i.e "n".In the for loop we have pass 2,n+1 which has been used to iterating the loop calculating factorial and string the result in the result variable In the main function we have pass the range on which we have to calculated the factorialFinally the print function will print the factorial .

Following are the attachment snip of code in the python language

By filling in the blanks to make the factorial function return the factorial of n, we have the following.

def factorial (n):

 result = 1

 for x in range(2, n+1):

   result = result*x

 return result

for n in range(10):

 print(n,factorial(n))

The math module in Python includes a number series of mathematical operations that may be easily done using the module. The math . factorial() function computes the factorial of a given number.

To write the code perfectly and fill in the blanks:

We created a math factorial function with n parameterThis code is being passed through the iterating loop 2,n+1 for calculation. We string the result, perform the range, and print out the result using the print formula.

CODE:

def factorial (n):

 result=1

 for x in range(2, n+1):

   result = result*x

 return result

for n in range(10):

 print(n,factorial(n))

RESULT:

0 1

1 1

2 2

3 6

4 24

5 120

6 720

7 5040

8 40320

9 362880

Therefore, we can conclude that we've understood how to write the factorial function code in python.

Write a static method named contains that accepts two arrays of integers a1 and a2 as
parameters and that returns a boolean value indicating whether or not a2's sequence of
elements appears in a1 (true for yes, false for no). The sequence of elements in a2 may
appear anywhere in a1 but must appear consecutively and in the same order. For example, if
variables called list1 and list2 store the following values:

int[] list1 = {1, 6, 2, 1, 4, 1, 2, 1, 8};
int[] list2 = {1, 2, 1};

Then the call of contains(list1, list2) should return true because list2's sequence of
values {1, 2, 1} is contained in list1 starting at index 5. If list2 had stored the values {2,
1, 2}, the call of contains(list1, list2) would return false because list1 does not
contain that sequence of values. Any two lists with identical elements are considered to contain
each other, so a call such as contains(list1, list1) should return true.

The data are summarized as follows:

                                                       Sample 1             Sample 2

Sample size                                        n=20                    n=20

The test statistic is obtained from online calculator as

t=-0.23

The p-value is given by 0.821

As the p-value is more than 0.05, we fail to reject the null hypothesis at 5% level of significance and hence conclude that there is no statistically significant difference between the original website and the prototype developed by the team at 5% level of significance.
