Given two matrices A and B of size m x n and n x p, calculate C = A x B.
The matrix multiplication is defined as follows:
n
Cij = Σ Aik x Bkj
k=1
m n
A11 A12 ... A1n
...
Am1 Am2 ... Amn
n p
B11 B12 ... B1p
...
Bn1 Bn2 ... Bnp
Each entry is a positive integer no more than 20, and 0 < m, n, p < 10.
C11 C12 ... C1p
...
Cm1 Cm2 ... Cmp
Print each entry with "%d " (a number followed by a whitespace)
Note that there is a newline character at the end of the output.
