Q$1.$ Perform parallel merge sort on a $16-$element array. The $16-$element array would be

divided into two $8-$element arrays, and each one would be passed to a child process.

Similarly, the children would pass $4-$element arrays to their children and so on$.$ Each

process will wait for its children and then merge the resulting arrays using a merge

operation. Use pipes to pass data among processes. $[10$ pts$]$

Input: Define a $16-$element array in the code. The array must be unsorted.

Output: Print the initial unsorted array and the final sorted array.
