Hey,

I'm a beginner in competitive programming, training on CSES and Codeforces and I'm facing an issue with some CSES problems that seem impossible to solve in Python because of time limits, though I see others have done it according to the statistics.

After hours of struggling with the "Concert Tickets" problem and failing to pass the time limit, I'd like to know if anyone has tips, solutions, or editorials to help me pass it using Python3 compiled with PyPy3.

Thanks in advance!
