IEEEXtreme 17.0 Problems Discussion
Yesterday IEEEXtreme 17.0 was held, and there are a lot of problems to upsolve, so let's discuss problems here.
If there is a problem that you can't solve, maybe ask here and someone will help!
I will start with this problem, Cool Sum, I couldn't get more than 50% points and the only thing that came up online while searching for similar problems is “Generating Functions”, help.
