/**
 * This is a simple program that allows the user to enter strings,
 * and prints their hash codes.
 *
 * Since this is NOT a cryptographic hash, it is quite possible to
 * figure out what the string was from the hash.
 *
 * See challenge.txt for some output.  I've not written a solution myself,
 * so I don't know exactly how hard it is to crack all of them, but some of the
 * first ones should be easy.
 *
 * Hint: as in class, look at String.hashCode's Java implementation.
 *
 * Do your required work first! Then, you might have fun with this.
