Program hangs!
Description:
It's 3AM and you get the dreaded call from a customer: the program your company sold them is hanging. You eventually trace the problem down to a call to a function named mystery. Usually, mystery works fine and produces an integer result for an integer input. However, on certain inputs, the mystery function just locks up.
Unfortunately, the mystery function is part of a third-party library, and you don't have access to the source code. Uck. It may take a while to get support from the provider of the library, and in the meantime, your customer is getting frustrated.
Your mission, should you choose to accept it, is to create a new function called wrap_mystery that returns the same results as mystery, but does not hang. Since you're not sure exactly what values mystery should be returning for hangs, just have wrap_mystery return -1 for problematic input. Your customer is counting on you!
wrap_mystery will only be called with positive integers less than 1,000,000.
