In my Java class this semester, we went over the Towers of Hanoi problem during our study of recusion. The recusrive solution is elegant. It is also simpler than any iterative solution. We did not code a solution. We just studied one intently to understand the recursive nature of it.
Recently I saw one of the sample problems you need to solve during a Facebook interview. One of them is the Towers of Hanoi problem. Nice. Facebook even let's you code the thing in Java. It has to work correctly. And you need to complete the thing in 45 minutes.
Not sure if I can meet that metric. But at least I have seen the problem and solution before. I guess I could google the code. That would be cheating. I feel good about what my Java college class is teaching me.
Good-fast-cheap. Pick two. - I got invited to a meeting with the customer today. There was a problem in production. And the customer wanted answers. When it came time, I explained wha...
