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: $H$ $W$ $S_1$ $S_2$ $\vdots$ $S_H$ [samples]

Samples

Input #1

3 5
#....
.....
.##..

Output #1

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.

Input #2

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

Output #2

0

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

Input #3

6 5
