레이팅 미적용While playing in his favourite text editor, Daniel decided to draw a picture that was \(N\) characters high and
\(M\) characters wide. The picture consists solely of characters ’.’ and ’’ such that characters ’’ form
some non-overlapping rectangles. The rectangles don’t even touch each other on their sides or corners.
Help Daniel count the number of rectangles drawn on the picture.
In the test cases worth a total of 10 points, all rectangles will consist of a single ’*’ character.
In the test cases worth additional 15 points, it will hold \(N = 1\).
The first line contains two integers \(N\) and \(M\) (\(1 \le N\), \(M \le 100\)) from task description.
Each of the next \(N\) lines contains \(M\) characters ’.’ or ’*’ which represent the picture that Daniel drew.
In a single line you should output the number of rectangles on the picture.
