The easiest way is to first fill out the whole chessboard with characters # and ., the dimensions being $(U+M+D) \times (L+N+R)$ $(U + M + D) \times (L + N + R)$ , and then typing in Mirko's crossword puzzle. For both operations, we need a double for loop iterating through the matrix (or submatrix).

As for filling out the chessboard, the field $(i, j)$ $(i, j)$ will be # depending on the parity of $i+j$ $i + j$ . As for typing in Mirko's crossword puzzle, the field $(i, j)$ $(i, j)$ of Mirko's crossword puzzle from the input will be typed into the $(U+i, L+j)$ $(U + i, L + j)$ field of our chessboard.
