3360: A Multiply Problem

Our problem is,for a giving M rows and M columns matrix A,output another matrix B=A^N.

There are multiple test cases. The first line of the input contains an integer T, meaning the number of the test cases.
For each test cases, there are two integers M and N in a single line.
You can assume that 1<=M<=4,,0<=N<=4.

Then,M row M column integers value v followed.The ith row and jth column v represent a the ith row and jth column of matrix A.You can assume that for each v, -10<=v<=10.

For each testcase,first output the case number in a single line.Then,output M rows M columns integers represent the matrix B.

Each line of the output should contain M integers and these M integers should be separated by blank spaces.You must know no blank space after the last integer of each line.
