A - Pawn on a Grid

Score : $100$ points

Problem Statement

There is a grid with $H$ rows from top to bottom and $W$ columns from left to right. Each square has a piece placed on it or is empty.

The state of the grid is represented by $H$ strings $S_1, S_2, \ldots, S_H$, each of length $W$.
If the $j$-th character of $S_i$ is #, the square at the $i$-th row from the top and $j$-th column from the left has a piece on it;
if the $j$-th character of $S_i$ is ., the square at the $i$-th row from the top and $j$-th column from the left is empty.

How many squares in the grid have pieces on them?

Constraints

• $1\leq H,W \leq 10$
• $H$ and $W$ are integers.
• $S_i$ is a string of length $W$ consisting of # and ..

Input

The input is given from Standard Input in the following format:

$H$ $W$

$S_1$

$S_2$

$\vdots$

$S_H$

Output

Print the number of squares with pieces as an integer.

3

The following three squares have pieces on them:

• the square at the $1$-st row from the top and $1$-st column from the left;
• the square at the $3$-rd row from the top and $2$-nd column from the left;
• the square at the $3$-rd row from the top and $3$-rd column from the left.

Thus, $3$ should be printed.

1 10
..........

0

Since no square has a piece on it, $0$ should be printed.
