 Multiply Matrices
##### *School Problem's Submission isn't counted in score!

Given two square Matrices A[][] and B[][]. Your task is to complete the function multiply which stores the multiplied matrices in a new matrix C[][].

Input:
The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. Each test case contains an integer N denoting the size of the square
matrix . Then in the next two lines are N*N space separated values of the matrix A[][] and B[][].

Output:
For each test case in a new line output will be
the space separated values of the matrix C[][].

Constraints:
1 <=T<= 100
1 <= N <= 20

Example(To be used for the expected output):
Input:
2
