Sample Problems and Solutions

In order to be useful you should try to solve these sample problems with a time limit. Try to ensure that you completely finish the problem. It is very easy to say "I know how to do that", but if a similar problem comes up in the competition, you might find out that you didn’t really know it. Also remember that just because your program works for some sample input doesn’'t mean that it will work for all possible input.
