Given an integer array of which both first half and second half are sorted. The task is to merge two sorted halves of the array into a single sorted array. Note: The two halves can be of arbitrary sizes.
Example 1:
Input:
N = 6
arr[] = {2 3 8 -1 7 10}
Output: -1 2 3 7 8 10
Explanation: {2 3 8} and {-1 7 10} are sorted
in the original array. The overall sorted
version is {-1 2 3 7 8 10}
Example 2:
Input:
N = 5
arr[] = {-4 6 9 -1 3}
Output: -4 -1 3 6 9
Explanation: {-4 -1} and {3 6 9} are sorted
in the original array. The overall sorted
version is {-4 -1 3 6 9}
Your Task: You don't need to read input or print anything. Your task is to complete the function sortHalves () which takes the array arr[] and its size n as inputs and modifies the array such that it gets sorted completely.
Expected Time Complexity: O(n). Expected Auxiliary Space: O(n).

Avoid using static/global variables in your code as your code is tested
against multiple test cases and these tend to retain their previous values.
Passing the Sample/Custom Test cases does not guarantee the correctness of code.
On submission, your code is tested against multiple test cases consisting of all
possible corner cases and stress constraints.
