Given a matrix with 0’s and 1’s , you enter the matrix at cell (0,0) in left to right direction. whenever you encounter a 0 you retain in same direction , if you encounter a 1’s you have to change direction to right of current direction and change that 1 value to 0, you have to find out from which index you will leave the matrix at the end.

**Input:**

The first line of input contains an integer T denoting the no of test cases. Then T test cases follow. Each test case contains two lines . The first line of each test case contains two integers n and m denoting the size of the matrix. Then in the next line are n*m space separated values of the matrix.

**Output:**

For each test case print in a new line two integers separated by space denoting the index of the matrix from which you will leave the matrix at the end.

**Constraints:**

1<=T<=100

1<=n,m<=20

**Example:
Input:**

2

3 3

0 0 1 0 0 0 0 0 0

2 4

0 0 0 1 0 0 1 1

2 2

0 2
