I'd say yes; instead give him/her pseudocode and some pointers to help get him/her going.

Okay, the idea I used was keeping track of the current position of a "cursor" and also keeping track of "walls."

There is of course the top wall, the bottom wall, the left wall, and the right wall. You'll also have to keep track of the "cursor" (or your) position.

You can imagine that you start at the top-left corner, and you walk down, until you hit a wall. Then you turn, and walk, until you hit the next wall. You keep going like this. However, every time you hit a wall and start towards another direction, you have to pull the wall behind you in by 1, to make sure you don't ever walk through squares you already walked through. When you walk the m * n number of paces - with m and n being the width and height of the matrix - you're done spiraling in through the matrix.


Here's what I mean:

I hope this helps, and that you understood what I mean. So now you just have to write the formulas and algorithms and functions. Should you have any further questions, you can post them here (which I think you already know anyway :D, but this sounds more professional :cool:).
