### Problem

Write a program to compute the product of two matrices A and B that are multipliable in the form of AB.

### Input

The first line of input is the number of all the test cases that follow.
For each test case, there are three positive integer m, n, p (m, n, p <= 100) on the first line,
meaning that A's dimension is m rows by n columns while B's is n rows by p columns.
Then comes the data of matrices A and B. Matrix A is represented by m lines of integers
ranging in [-1000, 1000], with each line containing n integers separated by a space.
A line is corresponding to a row of a matrix.
The data format for matrix B is much the same except for its potentially different dimensions.
Please refer to the section **Sample Input**.

### Output

For each test case, print the product of A multiplied by B in the form described in the section **Input**,
but do not include any dimension description.

### Sample Input
