24649번 - Letters Q and F 다국어

문제

Little Lev is learning how to draw letters Q and F. Initially, he has a white grid of size $n \times m$. Then he will draw several letters of one of the following two shapes:

Lev will not rotate or mirror these two shapes. Every time he draws a new letter, he will choose a position for the letter inside the grid and paint all cells of the shape black. Lev will only draw letters in such a way that before drawing all black cells of the letter are white --- that is, he will never paint a cell twice.

You are given the final coloring of the grid. Count the number of letters Q and letters F drawn by Lev.

입력

The first line contains two integers $n$ and $m$ --- the height and the width of the grid (5ドル \le n \le 300$; 3ドル \le m \le 300$).

The next $n$ lines contain $m$ characters each, denoting the final state of the grid. A white cell is denoted by '.', a black cell is denoted by '\#'.

It is guaranteed that the grid is a valid result of Lev's drawing.

출력

Print two integers --- the number of letters Q and the number of letters F drawn by Lev, respectively.
