There is a grid with H rows and W columns. Let (i,j) denote the square at the i-th row from the top and the j-th column from the left. Initially, there was one cookie on each square inside a rectangle whose height and width were at least 2 squares long, and no cookie on the other squares. Formally, there was exactly one quadruple of integers (a,b,c,d) that satisfied all of the following conditions. 1≤a<b≤H 1≤c<d≤W There was one cookie on each square (i,j) such that a≤i≤b,c≤j≤d, and no cookie on the other squares. However, Snuke took and ate one of the cookies on the grid. The square that contained that cookie is now empty. As the input, you are given the state of the grid after Snuke ate the cookie. The state of the square (i,j) is given as the character S i,j ​ , where # means a square with a cookie, and . means a square without one. Find the square that contained the cookie eaten by Snuke. (The answer is uniquely determined.)

To solve this problem, we can iterate over all possible positions of the removed cookie and check if the remaining cookies form a valid rectangle. We can start by iterating over all possible ...
