Ans. 
Bubble Sort algorithm is used to sort an array of non-negative integers in non-decreasing order.
• Implement the Bubble Sort algorithm to sort the array in place.

• Compare adjacent elements and swap them if they are in the wrong order.

• Repeat this process until the array is sorted.

• Time complexity of Bubble Sort is O(n^2) in the worst case.

• Example: For input [6, 2, 8, 4, 10], the output should be [2, 4, 6, 8, 10].
