A session would generally be conducted by CodeChef volunteers and would be a live discussion (via text + video). The main purpose of these sessions would be to discuss the theory topics and then move on how to go about solving problems.
This will be a two-part session with a review of basic ideas of combinatorics (such as counting principles, permutations, combinations, recursion in combinatorics, the principle of inclusion-exclusion and others) along with some problems + QnA.
For part 2, the following topics will be discussed:
- Circular Permutations
- The Principle of Inclusion and Exclusion and Derangement
- Computing nCr
- Combinatorial proof of the Binomial Theorem (if time permits)
- Problem solving, DP and Recursion in Combinatorics
You can comment if you want any specific topic or problem (possibly from INOI).
Minimum pre-requisites: Basic arithmetic, Topics from part 1.
Recommended pre-requisites: familiarity with recursion and set theory.
5:00 PM IST, 6th August 2020 (Thursday)
Platform for video conferencing:
Zoom Meetings limited 100 seats. Entry to the session on Zoom will be on a first come first serve basis.
Rest of the participants can join live on CodeChef’s YouTube channel .
