bobo hates big integers. So you are only asked to find the result modulo 3.
输入
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).
输出
For each tests:
Print n lines. Each of them contain n integers -- the matrix A×B in similar format.
