HAOI2018 has ended, I didn't get to join the team...
The quality of the questions is still good, there are no major problems, and I have successfully distinguished a violent player like me...
There are too many regrets and things to say, but I can only wait It's next year...
This blog is about to be maintained, mainly for the summary and solution of the usual practice questions, most of which are related to OI. It will be easier to review in the future, and I hope to give some reference and help to the struggling OIer...
