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

  1. Declare and initialize an array.
  2. Loop through the array and select an element.
  3. Inner loop will be used to compare selected element from outer loop with rest of the elements of array.
  4. If any element is greater than the selected element then swap the values.
  5. Continue this process till entire list is sorted in descending order.

Solution

Python

Output:

Elements of original array: 
5 2 8 7 1 
Elements of array sorted in descending order: 
8 7 5 2 1 

C

Output:

Elements of original array: 
5 2 8 7 1 
Elements of array sorted in descending order: 
8 7 5 2 1 

JAVA

Output:

Elements of original array: 
5 2 8 7 1 
Elements of array sorted in descending order: 
8 7 5 2 1 

C#

Output:

5 2 8 7 1 
Elements of array sorted in descending order: 
8 7 5 2 1
