• There will be no submission limit.
• Ties in score will be broken by the last submission time that increased your score.

Before the contest date, you may wish to check out the tips and help pages.

We have listed below some advice as well as contest strategies:

• Problems will be approximately increasing in difficulty. Reading all of the statements is still recommended.
• Remove all extra debugging code and/or input prompts from your code before submitting. The judge is very strict — most of the time, it requires your output to match exactly.
• Do not pause program execution at the end. The judging process is automated. You should use stdin / stdout to perform input / output, respectively.
• It is guaranteed that all problems and subtasks will be solvable in C++ and Java; Python users are recommended to use PyPy.
