Programming Challenges

Welcome to the CS Tutoring Center programming problems page! Here, you will find our list of programming challenges.

You are NOT restricted to using C++ or Java. You may use ANY programming language of your choosing but all of these programming challenges can be solved by using either C++ or Java. You may even solve these by paper and pencil, the good old fashioned way. There are also some problems that can be solved with a scientific calculator. If you're serious about HTML/PHP programming you'll need a reliable dedicated server to host your scripts.

If anyone has any suggestions for a problem, contact us and who knows, we might just use it. Remember, a submission counts as 100 rewards points for a regular member but 200 points for a premier member!

In order to submit answers to the problems, please register here for FREE.. This will allow you to keep track of your rating as well as the problems you have solved.

For some open ended challenges, try some of the previous questions Microsoft has asked on an interview. See if you have what it takes to be hired by them...No solutions to the interview questions are provided.
