A program to introduce you to debugging.

In this program, there are three bugs. You have to find them, and fix them. You have to do this as systematically as possible:

• Tighten the loop (find the exact line the bug is coming from)
• Get some insight (use p to inspect everything in the region of that line)
• Once you know the one thing that is wrong, out of place, misspelled, or not giving you what you expect, try to fix it.

Wisest is he who tries only one thing to fix the problem. Faffing about trying whatever occurs to you next is a recipe for development hell.
