Reverse an Array in Groups of Given Size
Given an array of integers and a size k, Reverse every sub-array of k group elements. In this tutorial, I have explained a java code to reverse an array in groups of given size.
Example1 :
Input: {1, 5, 7, 2, 3, 6, 7, 8, 9}, k = 3
Output: {7, 5, 1, 6, 3, 2, 9, 8, 7}
Example2 :
Input: {1, 2, 3, 4, 5, 6, 7, 8}, k = 5
Output: {5, 4, 3, 2, 1, 8, 7, 6}
