Can anyone provide some tricky test? It's such a troublesome code.

1) Does bumping into mean robot and person cannot be in *adjacent" squares? Or just that they cannot be in same square?

2) Can robots see through each other?

3) What's wrong with NNWXNWWSW for my 3rd example? why a longer path is required? I simulate this and it looks perfectly fine to me.

Thanks!

1) They cannot be in the same square. So, you cannot move into a square occupied by a robot.
2) The movement of a robot doesn't depend on the other.
3) I guess it is related to my point 1)?

Thanks! Got accepted.
