Write a pseudocode method swap(aList, i, j) that interchanges the items currently in positions i and j of a list. Define the met

hod in terms of the operations of the ADT list, so that it is independent of any particular implementation of the list. Assume that the list, in fact, has items at positions i and j. What impact does this assumption have on your solution

Answer:

Explanation:

The following pseudocode for this method using operations of the ADT list would be the following

swap(aList, indexI, indexJ) {

    initialize temp_variable = Retrieve(indexI, aList)

    Insert(Retrieve(indexJ, aList), indexI, aList)

    Insert(Retrieve(indexI, aList), temp_variable, aList)

}

This code basically saves the aList index of i , into a temporary Variable. Then it sets the aList index of i to the value of the element in index of j. Then it does the same for the index of j with the tem_variable. If we assume that the indexes of i and j exist, then it can crash our entire program if those indexes are missing from the list when we try to access them.

Hence, the correct option is c.

devlian [24]

Ad libitum [116K]

Answer:

Following are the correct python code to this question:

n1 = float(input('Input first number: '))#input first number  

n2 = float(input('Input second number: '))#input second number  

n3 = float(input('Input third number: '))#input third number  

n4 = float(input('Input fourth number: '))#input fourth number  

average = (n1+n2+n3+n4)/4 #calculate input number average

product = n1*n2*n3*n4 # calculate input number product

print('product: {:.0f}  average: {:.0f}'.format(round(product),round(average))) #print product and average using round function

print('product: {:.3f}  average: {:.3f}'.format(product,average)) #print product and average value

Output:

Please find the attachment.

Explanation:

The description of the above python code can be defined as follows:

  • In the above python program four variable "n1, n2, n3, and n4" is defined, in which we take input from the user end, and in these user inputs we use the float method, that converts all the input value in to float value.
  • In the next step, two variable average and product are defined, that calculate all input numbers product, average, and hold value in its variable.
  • In the last line, the print method is used, which prints its variable value by using a round and format method.
