Answer 2

Given an array (or string), the task is to reverse the array/string.

Input : arr[] = {1, 2, 3}

Output : arr[] = {3, 2, 1}

Input : arr[] = {4, 5, 1, 2}

Output : arr[] = {2, 1, 5, 4}

1) Initialize start and end indexes as start = 0, end = n-1

2) In a loop, swap arr[start] with arr[end] and change start and end as follows :

start = start +1, end = end – 1
