# Exit Point Of A Matrix

easy

1. You are given a number n, representing the number of rows. 2. You are given a number m, representing the number of columns. 3. You are given n*m numbers (1's and 0's), representing elements of 2d array a. 4. Consider this array a maze and a player enters from top-left corner in east direction. 5. The player moves in the same direction as long as he meets '0'. On seeing a 1, he takes a 90 deg right turn. 6. You are required to print the indices in (row, col) format of the point from where you exit the matrix.

## Constraints

1 <= n <= 10^2 1 <= m <= 10^2 e1, e2, .. n * m elements belongs to the set (0, 1)

## Format

### Input

A number n A number m e11 e12.. e21 e22.. .. n * m number of elements

### Output

row col (of the point of exit)
