You write steps for a robot that makes a toasted cheese sandwich:
- Take 2 slices of bread.
- Spread 1 spoon of butter on one slice.
- Place 3 slices of cheese on the buttered slice.
- Put the other slice on top.
- Toast the sandwich until it is done.
- Cut it into 2 equal halves.
The robot follows steps exactly and never guesses. Which step would it get stuck on?
Enter the step number (a whole number from 1 to 6).
