## MPOW - Power of matrix

You will be given a square matrix M and a positive integer power N. You will have to compute M raised to the power N. (that is, M multiplied with itself N times.)

### Input

First line of input is T ( number of test-cases) First line of each test-case contains two integer M , N where M is size of square matrix that we have to exponent and N is the power to which we have to exponent
Next M lines describe the input matrix. Each line contains exactly M elements corresponding to each array

### Output

Output M line corresponding to each row of resultant matrix Each line must have M integers where jth element of ith line is jth element of resultant matrix taken modulo with 1000000007 (10^9+7).

Simply , you have to print the resultant square matrix.

### Example

```Input:
2
2 3
1 0
1 1
3 3
1 0 4
1 2 2
0 4 4
```
```Output:
1 0
3 1
17 112 116
15 88 100
28 144 160
```

constraints:

1<=T<=10

1<=M<=50

1<=N<=100000

0<=each element of input matrix<=10^9
