Q. Program to sort the elements of an array in descending order.ExplanationIn this program, we need to sort the given array in descending order such that elements will be arranged from largest to smallest. This can be achieved through two loops. Outer loop will select a element and inner loop allow us to compare selected element with rest of the elements. Original array: Array after sorting: Elements will be sort in such a way that largest element will appear on extreme left which in this case is 8. Smallest element will appear on extreme right which in this case is 1. Algorithm
SolutionPython#Initialize array arr = [5, 2, 8, 7, 1]; temp = 0; #Displaying elements of original array print("Elements of original array: "); for i in range(0, len(arr)): print(arr[i]), #Sort the array in descending order for i in range(0, len(arr)): for j in range(i+1, len(arr)): if(arr[i] < arr[j]): temp = arr[i]; arr[i] = arr[j]; arr[j] = temp; print(); #Displaying elements of array after sorting print("Elements of array sorted in descending order: "); for i in range(0, len(arr)): print(arr[i]), Output: Elements of original array: 5 2 8 7 1 Elements of array sorted in descending order: 8 7 5 2 1 C#include Output: Elements of original array: 5 2 8 7 1 Elements of array sorted in descending order: 8 7 5 2 1 JAVApublic class SortDsc { public static void main(String[] args) { //Initialize array int [] arr = new int [] {5, 2, 8, 7, 1}; int temp = 0; //Displaying elements of original array System.out.println("Elements of original array: "); for (int i = 0; i < arr.length; i++) { System.out.print(arr[i] + " "); } //Sort the array in descending order for (int i = 0; i < arr.length; i++) { for (int j = i+1; j < arr.length; j++) { if(arr[i] < arr[j]) { temp = arr[i]; arr[i] = arr[j]; arr[j] = temp; } } } System.out.println(); //Displaying elements of array after sorting System.out.println("Elements of array sorted in descending order: "); for (int i = 0; i < arr.length; i++) { System.out.print(arr[i] + " "); } } } Output: Elements of original array: 5 2 8 7 1 Elements of array sorted in descending order: 8 7 5 2 1 C#using System; public class SortDsc { public static void Main() { //Initialize array int [] arr = new int [] {5, 2, 8, 7, 1}; int temp = 0; //Displaying elements of original array Console.WriteLine("Elements of original array: "); for (int i = 0; i < arr.Length; i++) { Console.Write(arr[i] + " "); } //Sort the array in descending order for (int i = 0; i < arr.Length; i++) { for (int j = i+1; j < arr.Length; j++) { if(arr[i] < arr[j]) { temp = arr[i]; arr[i] = arr[j]; arr[j] = temp; } } } Console.WriteLine(); //Displaying elements of array after sorting Console.WriteLine("Elements of array sorted in descending order: "); for (int i = 0; i < arr.Length; i++) { Console.Write(arr[i] + " "); } } } Output: Elements of original array: 5 2 8 7 1 Elements of array sorted in descending order: 8 7 5 2 1 PHP<!DOCTYPE html> <html> <body> <?php //Initialize array $arr = array(5, 2, 8, 7, 1); $temp = 0; //Displaying elements of original array print("Elements of original array: <br>"); for ($i = 0; $i < count($arr); $i++) { print($arr[$i] .
