1127: matrix product

Title Description

Computes the product of two matrices A and B.

Entry

The first line of three positive integers m, p and n, 0 <= m, n , p <= 10, A represents a matrix of m rows and p columns, the matrix B is p rows and n columns;
next row is m matrix A content, each row integers p, separated by spaces;
final content of p rows of matrix B, n integers each row, separated by spaces.

Export

Product matrix output: output accounted for m rows, each row of n data, separated by a space.
