Let us draw something together. There is an empty grid with a size 5 by 5, like so:

▢ ▢ ▢ ▢ ▢
▢ ▢ ▢ ▢ ▢
▢ ▢ ▢ ▢ ▢
▢ ▢ ▢ ▢ ▢
▢ ▢ ▢ ▢ ▢

I will give you instructions like "put an X in the top left", and you return the grid by applying the given instruction, like so:

Instruction: put an X in the top left

X ▢ ▢ ▢ ▢
▢ ▢ ▢ ▢ ▢
▢ ▢ ▢ ▢ ▢
▢ ▢ ▢ ▢ ▢
▢ ▢ ▢ ▢ ▢

Now create an empty grid with a size 5 by 5 and execute the following commands at each step. Once you execute the command, return only the grid and exclude all other text from the output.
