For Assignment 3, the auto-responder will be looking for the following
files. To submit, just cut-and-paste your code in as usual, with the
standard delimiters ("!!") indicating filenames.

Problem 1

intset.h - even if you didn't change it
intset.cpp - your implementation of the intset class

Note that you do not need to submit a file with a main( ) function, as I
will use my own to test the IntSet class.

Problem 2

list.h - declarations for class List
list.cpp - implementation of class List
state.h - declarations for class State
state.cpp - implementation of class State
puzzle.cpp - your main file that will show an example of solving an 8
puzzle
