Mirko has assembled an excellent crossword puzzle and now he wants to frame it. Mirko's crossword
puzzle consists of M x N letters, and the frame around it should be U characters wide on top, L
characters on the left, R characters on the right and D characters on the bottom side.
The frame consists of characters # (hash) and . (dot) which alternate like fields on a chessboard. These
characters should be arranged in a way that, if the frame is expanded to cover the entire crossword
puzzle and we treat these characters as a chessboard, the # characters should be placed as the red fields
on a chessboard (i.e. the top left field). See the examples below for a better understanding of the task.
The first line of input contains two integers M and N (\(1 \le M\), \(N \le 10\)).
The second line of input contains integers U, L, R, D (\(0 \le U\), L, R, \(D \le 5\)).
The following M lines of input contains N characters – lowercase letters of the English alphabet. These
lines represent Mirko's crossword puzzle.
Output the framed crossword puzzle as stated in the text.
