In this video we will see how to reverse an array in groups of a given size. Say for a given size of 3, we are to reverse the first 3 elements of the array. And then the next three and so on.

Example: Input: arr = [1, 2, 3, 4, 5, 6, 7, 8, 9] k = 3 Output: [3, 2, 1, 6, 5, 4, 9, 8, 7]

Check out the video to see how we implement this!!
