3 Exercise: Matrix Multiplication To compute C = A  B, where A, B, C are matrices  c i,j = (a i,1  b 1,j ) + (a i,2  b 2,j ) (a i,n  b n,j )  c i,j is sum of terms produced by multiplying the elements of A’s row i with B’s column j. Example on 3  3 matrices:  Please refer to MatricesSolution.java
