He has been engaged in algorithm competitions for five years, but his rating is still a newbie. Sometimes, he can't even solve a problem in div2. It stands to reason that the algorithm competition is not suitable for him, he should give up, but he still persevered, and it lasted for five years. I am very moved by this love of algorithm competitions. Yes, his id is rainboy.

This. . . I just want to liven up the atmosphere. .
Welp, sorry for offending you, but FYI, his real name is Rain Jiang, and you can find out his performance in USACO on Google.
