# Program to copy the contents of one array into another in the reverse order

Given an array, the task is to copy these array elements into another array in reverse array.

Examples:

```Input: array: 1 2 3 4 5
Output: 5 4 3 2 1

Input: array: 10 20 30 40 50
Output: 50 40 30 20 10
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Let len be the length of original array. We copy every element original_arr[i] to copy_arr[n-i-1] to get reverse in copy_arr[].
