Multithreaded Programming: You will write a multithreaded program to short a large integer array. Your application will have a main thread whose job is to read the data from a file into an array and delegate the sorting function to 2 threads. Each created thread will sort half of the array. When both child threads are done with the sorting, the parent thread will merge these two sorted subarrays and write the sorted array into.(Hint: for merge operation, see mergesort in your data structure books) Child threads may use the same sort function or each may sort its portion of array using dierent sort algorithms. I leave the decision to you.
