[OFFICIAL] Live DSA Learning - Basic Combinatorics (Part 1) - Session 11

Hi everyone,

This is a continuation of the Live DSA learning sessions being conducted as part of the DSA Learning series .

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 1, the following topics will be discussed:

  • The fundamental counting principles
  • A quick recap of factorials
  • The principle of Bijection
  • Permutations
  • Combinations
  • Problems based on these ideas

You can comment if you want any specific topic or problem (possibly from INOI).

  • Pre-requisite:
    Minimum pre-requisites: Just basic arithmetic.
    Recommended pre-requisites: familiarity with recursion and set theory.
  • Session volunteer:
    Aryan Mediratta
  • Date-Time:
    4:00 PM IST, 11th July 2020 (Saturday)
  • Duration:
    ~1.5 hours
  • 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 .
  • Note from CodeChef:
    — These sessions are hosted by our volunteers. Kindly respect their efforts and time.
    — In case of any doubts, please post in the comments.
