9. Write a program to multiply two matrices that uses threads to divide up the work necessary to compute the product of two matrices. There are several ways to improve the performance using threads. You need to divide the product in row dimension among multiple threads in the computation. That is, if you are computing A * B and A is a 10 x 10 matrix and B is a 10 x 10 matrix, your code should use threads to divide up the computation of the 10 rows of the product which is a 10 x 10 matrix. If you were to use 5 threads, then rows 0 and 1 of the product would be computed by thread 0, rows 2 and 3 would be computed by thread 1,...and rows 8 and 9 would be computed by thread 4.
