problem no 49:sorting problem:sort the array if the first half and the second half of the array is sorted.

QUESTION:

 

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}

ANSWER:

void sortHalves (int arr[], int n)
        {
            sort(arr,arr+n);
        }
