#P4920. Matrix multiplication

Matrix multiplication

Problem Description

Given two matrices A and B of size n×n, find the product of them.

bobo hates big integers. So you are only asked to find the result modulo 3.

Input

The input consists of several tests. For each tests:

The first line contains n (1≤n≤800). Each of the following n lines contain n integers -- the description of the matrix A. The j-th integer in the i-th line equals Aij. The next n lines describe the matrix B in similar format (0≤Aij,Bij≤109).

Output

For each tests:

Print n lines. Each of them contain n integers -- the matrix A×B in similar format.

1 0 1 2 0 1 2 3 4 5 6 7
0 0 1 2 1
