Your input and output may be a multiline string or a list of strings. If your language represents strings as lists of characters, you may substitute "list of characters" for "string" in the previous sentence. If your language needs to input the height and/or width of the grid, you may do so. Your output may (optionally) have a single trailing newline. As mentioned above, you may use any three distinct characters in place of #.o (please specify in your submission which characters you're using).
