The NSA Challenge of the Month tests your programming skills to the max! Each month a new problem will be featured and competitors have three weeks to write a program that gets the highest score. Your goal is to come up with an approximate solution which gets as close to perfection as possible using only the given information.

Check back often to view current scores and once the three weeks are up, be sure to see the results and view how others solved the problem.

You can learn more about these types of problems here. You can even practice here.
