I just finished the Stack section of Cracking the Coding Interview and came across an old puzzle - The Tower of Hanoi. I struggled with solving this problem. I wrote this elaborate, strange algorithm to try to solve it (which should have been a dead give-away that I had it wrong). Ironically enough, hidden in the 20-30 lines of code I wrote were the three lines of code I needed to solve the problem. Anyways, after beating my head in trying to solve this, I ended up going to the back of the book…
I read that you learn more from a poor example than from a correct one. I don't believe this but that means my site will be a success.
