## Goal

The goal of this puzzle is to find a pirate's treasure. The pirate surrounded his treasure by obstacles.
Input

**Line 1:** Width `W` of the treasure map.

**Line 2:** Height `H` of the treasure map.

**Next **`H` lines: `W` symbols (**0** or **1**) indicating free space (**0**) or obstacle (**1**).

Treasure is placed on free space surrounded by only obstacles.

There are three possible ways in which the treasure can be surrounded:

By **3** obstacles when the treasure is in the corner of the map.

By **5** obstacles when the treasure is on the edge of the map.

By **8** obstacles when the treasure is inside the map.

Output

The coordinates of the treasure on the map are represented by indices separated by a space. For example: "12 5"

Position "0 0" is in the top left corner, so the maximum index **x** is `W-1` and the maximum index **y** is `H-1`.

Constraints

* 2 <= `W` <= 25

* 2 <= `H` <= 25

* Only 1 treasure in map.
