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

The input consists of several tests. For each tests:

The first line contains n (1n800). 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 (0Aij,Bij109).

For each tests:

Print n lines. Each of them contain n integers -- the matrix AB in similar format.
