Purpose


Programming problems are a great way to prepare for contests, practice your coding skills, and exercise problem solving. With that in mind, a new problem from DMOJ will be posted here every Thursday. By participating in and solving these problems, you will earn points that go towards year-end prizes. You don't have to make a commitment to participate every week (because who has time for that at Central?); simply try a problem at home when you have time, or come in during one of our meetings and solve it with the help of your peers.
