ps11: can someone post a solution through problem 3? My implementation of updatePositionAndClean(self) is pretty dense and I have a bug I can't figure out. code here: http://codepad.org/DZR49b59#comment-bdYKRDeo

There's a while loop in lns 234-268 that is pretty dense, but that doesn't seem to be the problem. I posted the output in a comment at the bottom of the page.

figured it out -- my code breaks if a robots position is at 0,0 or max,max. Is there an easier way to do what I'm doing in the while loop?

anonymous · Answer

actually, i'm not sure that's the problem. There was a problem where a robot could be initialized to position 0,0 or max,max, but I took care of that and I'm still getting errors that the program tries to set the robots position outside of the room

this guy posted complete solutions. I working on PS11 myself, so I haven't looked, but his solutions to other problem sets have been very good (I think he's a professional programmer ... which would explain why they're so good). https://github.com/sebrenner/Mit-6.00-OCW-Problem-Set-Solutions#readme
