Akin's blog

By Akin, 4 years ago, In English,

There are many good blogs in Codeforces Blog where people describes about different Algorithm and Data Structures .

Lets gather all the resources about Algorithm and Data Structures Explanations. You can comment bellow the link and about it . I will always update that post gather new resources.Hope ,its help all and inspire all to write new blog post in future :)

    When I see such list with a lot of tutorials/problems, I always want to ask: have you read it, or you just posted it?

      My answer depends on your definition of "have you read it" .

First of all thank you for including my blog into this list.

The formatting of my blog is completely messed up now. I need to some day sit down and correct it :)

What about making a wiki page to give anyone permission to update them. For example, wiki page of Lazarus. In Lazarus page, there are a large number of trickS and tips in application developing.

    That sounds great!

    Can you provide Lazarus page?

This list are going to be too long. I think you should divide the list into sections, for instance, algorithm and data structure.

Maybe this and this

Btw, can you make links relative, please?

(/blog/entry/xxx instead of codeforces.com/blog/entry/xxx then it will be ok for .ru users)
