Programming Contest Detailed Syllabus Along with Example Problems

Competitive Programming Syllabus

Note that in general, the syllabus for Competitive Programming is open-ended. For ACM ICPC, the syllabus is not mentioned anywhere, whereas IOI syllabus is specified before the start of the contest each year. The below syllabus is kind of detailed topics from which you may face questions in competitive programming related competitions.

  • Euler Tour/Path (WORDS1 on SPOJ)
  • Suggested reading for most of the topics in Graph algorithms -

There is no such thing as “Syllabus for competitive programming”. Though, the list is quite exhaustive and helpful but the title is of course ridiculous.

Very Nice and Helpful.Thanks to the team for the effort.

what should be the order in doing this course

Very helpful

Added a comment, in the beginning, to clarify this up.

Thanks admin!!

The syllabus is majorly taken from here:

Was that prepared by Codechef? If not, then I think credits should be given rather than posting falsely here as it is.

Why do you think it was falsely posted? The link to the original doc was given in the References section.

Fixed now.

I thought that because at the time I posted that comment, the link was not working. Thanks for the fix :slight_smile:

Aho Corasick pdf link is broken (under strings section).

Awesome Content for ICPC preparation
