Thread: Help - Walk in a bidimensional array

Are you saying that? I'm trying to write a program that says that but I can't

You can use either a for or a while or a do while loop. They all can be made to work in place of the other. I like the for loop for this one.

You turn right on square one, and enter the loop.

Code:

start the loop: (stop the loop when you have no more empty squares) {
   You walk straight ahead. 
   (either the end of the array has been reached, or the square in front of you has a "been visited" value in it)
    If (you can't walk in that direction any more, && you have an empty square on your right)
       You turn right
}

Give it some work, Juan!

Isn't that a thing of simple "noir" genre beauty?
