Problem statement

Given an array with N elements, the task is to reverse all the array elements and print the reversed array.

Detailed explanation ( Input/output format, Notes, Images )

Input Format:

The first line contains an integer N representing the size of the array.

The second line contains N space-separated integers representing the elements of the array.

Output Format:

The only line of the output prints N space-separated integers representing the Reversed array elements.

Constraints:

1 <= N <= 10^3
1 <= arr[i] <= 10^9
1 <= K < N

Sample Input:

8
7 5 2 11 2 43 1 10

Sample Output:

10 1 43 2 11 2 5 7

Explanation of Sample Input:

Here the elements have been reversed.

Approach 1

Brute Force approach

Initialise start and end indices with start = 0, end = N-1 where N is the total number of elements in array.
We then run a loop while start < end and swap arr[start] with arr[end].
Finally, we increment start and decrement end variable
