Selection sort: The selection algorithm is used to sorts an array by continuously determining the minimum element from unordered portion and placing it at the starting position. The process of swapping in this sort may put one or more elements in its permanent place. Three steps in the selection sort algorithm are as follows: Finding whether the given array is sorted or not. Getting the index of the minimum value in the array. Performs swapping which is used to exchange the values in the two places. Algorithm execution flow: Initialize the value to the variable. Perform the loop until the first element is less than the length of a data array. Assign the index of the first element as a small value. Assign the index of the next element for the next value. Perform the loop until the index value is less than the length of a data array. Check each element with its next value to find a small value and set the index of small element to a variable. Increment the position of index value. After finding the small value, perform the swapping operation. Increment the value of position.

Chapter 7, Problem 63E

Program Plan Intro

Selection sort:

The selection algorithm is used to sorts an array by continuously determining the minimum element from unordered portion and placing it at the starting position.

The process of swapping in this sort may put one or more elements in its permanent place.

Three steps in the selection sort algorithm are as follows:

Finding whether the given array is sorted or not.

Getting the index of the minimum value in the array.

Performs swapping which is used to exchange the values in the two places.

Algorithm execution flow:

Initialize the value to the variable.

Perform the loop until the first element is less than the length of a data array.

Assign the index of the first element as a small value.

Assign the index of the next element for the next value.

Perform the loop until the index value is less than the length of a data array.

Check each element with its next value to find a small value and set the index of small element to a variable.

Increment the position of index value.

After finding the small value, perform the swapping operation.

Increment the value of position.

Methods (Ch6) - Review 1. (The MyRoot method) Below is a manual implementation of the Math.sqrt() method in Java. There are two methods, method #1 which calculates the square root for positive integers, and method #2, which calculates the square root of positive doubles (also works for integers). public class SquareRoot { public static void main(String[] args) { } // implement a loop of your choice here // Method that calculates the square root of integer variables public static double myRoot(int number) { double root; root=number/2; double root old; do { root old root; root (root_old+number/root_old)/2; } while (Math.abs(root_old-root)>1.8E-6); return root; } // Method that calculates the square root of double variables public static double myRoot(double number) { double root; root number/2; double root_old; do { root old root; root (root_old+number/root_old)/2; while (Math.abs (root_old-root)>1.0E-6); return root; } } Program-it-Yourself: In the main method, create a program that…
