tallnut_liu's blog

Here are some useful blogs I found in CodeForces.

Note that:

  • This list can be treated as an extension of catalog, since much of these tutorials are included in catalog but the others are collected by myself.
  • The same blog may be included in this post twice or more.
  • Blogs to ask questions are NOT included in this blog, since they seemed not quite useful to CP.
  • If there are any blogs that I have missed, please tell me in the comment section. Thank you very much.

Hint: you can use Ctrl+F to search for information here.
