Given a map of a dungeon, your task is to take all TWO diamonds in the dungeon.

Find the minimum number of gates you have to open to take all the diamonds.

Note: It can be more than one gate to go into the dungeon from the outside.

You can move up, down, left, right.

About the map:

  • The letter '.' means blank space, you can move on it

  • The letter '*' means blockade, you have to go around it

  • The letter '#' means there's a gate at that place, you need it opened to go through it

  • The letter '$' means the diamond.

Input format:

  • First line is two number N and M — the dungeon has the size N*M. (2 ≤ N,M ≤ 100)

Output format:

  • A single integer — the minimum number of gates you have to open.
