Who is rainboy?
By violentdoc, history, 3 years ago, In English

This question might be a little strange. But to me he is very mysterious.

There's few things I have noticed about rainboy,

  • He dominates in every contest he is participating or submitting trash willingly.
  • He has a very unusual rating graph. It is always making it's way up to the hill or falling down from it in a single contest.
  • He loves C language and his love for the C language is very unconditional. Same goes for competitive programming. The amount of submissions of the language C is outrageous. Maybe highest among all of the codeforces users.

  • While others are using languages with rich libraries, he is out there implementing like old school. Also he has the audacity to solve very hard data structure problems with the standard library he made for himself. (If you are interested, check out his submissions where he implemented a stl map or other stl data structures with C language for himself)

rainboy-tags

  • He is one of the most active problem solver in the server. He solved over three thousands problems in codeforces, I can not imagine what the total would be for the other platforms as well.
  • He is a Shrimp.

Although I know very little about rainboy, I want to say that his contribution in competitive programming and in C language is remarkable. And he is the definition of there's no language barrier in competitive programming.

Also, some of us are eagerly waiting for your "youtube appearance" or some comments from you or blogs would be fine.

He can go for LMG very easily, but I guess he likes his graph to be like how it is currently (raining)

    Yes, unlike usual, he submitted solutions starting with A. Interesting! I wonder if this will follow in future contests.

He is probably the most genius programmer of our time. While we are all trying to get the rating as high as possible, he just makes a rainbow!

        GL! Since you code in C, have a look over this. I found it very useful for advice, and also it discusses certain C things.

Even his Atcoder rating is pretty chaotic (although not as much as his codeforces rating) https://atcoder.jp/users/rainboy
