Write a pseudocode method swap(aList, i, j) that interchanges the items currently in positions i and j of a list. Define the method 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 1

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.

Write a function named square_list that takes as a parameter a list of numbers and replaces each value with the square of that value. It should not return anything - it should mutate the original list.

Answers

Answer:

The function is as follows:

def square_list(myList):

for i in range(len(myList)):

myList[i] = myList[i]**2

print(myList)

Explanation:

This defines the function

def square_list(myList):

This iterates through the list elements

for i in range(len(myList)):

This squares each list element

myList[i] = myList[i]**2

This prints the mutated list

print(myList)

write a java program that prompts the user to enter scores (each number an integer from 0 to 10) and prints the following output: how many scores entered the highest score the lowest score the average of all the scores the average with the highest and lowest score not counted if the user enters less than 3 scores print an error message instead of the output above

Answer:

Explanation:

The following is written in Java. It continues asking the user for inputs until they enter a -1. Then it saves all the values into an array and calculates the number of values entered, the highest, and lowest, and prints all the variables to the screen. The code was tested and the output can be seen in the attached image below.

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Scanner;

class Brainly {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

int count = 0;

int highest, lowest;

ArrayList<Integer> myArr = new ArrayList<>();

while (true) {

System.out.println("Enter a number [0-10] or -1 to exit");

int num = in.nextInt();

if (num != -1) {

if ((num >= 0) && (num <= 10)) {

count+= 1;

myArr.add(num);

} else {

System.out.println("Wrong Value");

}

} else {

break;

}

if (myArr.size() > 3) {

highest = myArr.get(0);

lowest = myArr.get(0);

for (int x: myArr) {

if (x > highest) {

highest = x;

}

if (x < lowest) {

lowest = x;

}

System.out.println("Number of Elements: " + count);

System.out.println("Highest: " + highest);

System.out.println("Lowest : " + lowest);

} else {

System.out.println("Number of Elements: " + count);

System.out.println("No Highest or Lowest Elements");

}
