Given 2 sorted arrays Ar1 and Ar2 of size N each. Merge the given arrays and find the sum of the two middle elements of the merged array.

Example 1:

Input:
N = 5
Ar1[] = {1, 2, 4, 6, 10}
Ar2[] = {4, 5, 6, 9, 12}
Output: 11
Explanation: The merged array looks like
{1,2,4,4,5,6,6,9,10,12}. Sum of middle
elements is 11 (5 + 6).
