Write a multithreaded program to compute sum of elements of NxN matrix. It should be done in two phases.

Phase I: Create N threads to compute 'N' Columns sum, where 'i' th thread computes a 'i' th column sum.

Phase II: Create a thread to compute sum of 'N' Column's Sums.

Finally main thread is going to print result.

Note: Main thread should wait till all threads completes their work.

You can use Math.random() to initialize NxN matrix, in the range 0 to 100; 5<><>
