Follow the instructions on each line.

Unless otherwise specified, continue to the next line after each instruction.

Get a blank piece of paper, and black and yellow pens.

Unless otherwise specified use the black pen for drawing.

Draw a three by three grid called "grid" where:
the top row is row 0,
the middle row is row 1,
the bottom row is row 2,
the left column is column 0,
the middle column is column 1,
the right column is column 2.

Draw a box called "x" and put 0 in it.

Draw a box called "y" and put 0 in it.

This line is labelled KETCHUP. Please continue.

If the number in box "y" is 3, go to the line labelled PICKLE. Otherwise continue.

This line is labelled MUSTARD. Please continue.

If the number in box "x" is the same as the one in box "y", skip the next line.

Find the spot in "grid" where the column is what's in "x" and the row is what's in "y" and
color it yellow.

Increase the number in box "x" by one.

If the number in box "x" is not 3, go to the line labelled MUSTARD. Otherwise continue.

Replace the number in box "x" with 0.

Increase the number in box "y" by one.

Go to the line labelled KETCHUP.

This line is labelled PICKLE. Please continue.

Replace the number in box "y" with 1.

Find the spot in "grid" where the column is what's in "x" and the row is what's in "y" and
color it black.

Stop.

That looks correct. Congratulations, you are a computer!
