Hello Codechef community,
We have initiated a series of videos to help every competitive programmer gain and grow faster.
The first topic which every programmer should know is Algebra required for Competitive Programming and the first fundamental topic in Algebra for Competitive programming is Binary Exponentiation and its applications.

Update3:- 4th topic in Algebra required for CP is Number Theoretic Function which includes Euler totient function and how to find the number of divisors.

  1. Binary Exponentiation
  2. Euclidean Algorithm
  3. Classical Sieve of Eratosthenes
  4. Number Theoretic Functions
    (UPDATE)
    Do check the description of the video for Practice Problems and details.

Do check this out and if you have any doubts do comment in this blog post.
The next topics for Algebra for Competitive Programming will be updated soon.

Thank You!!

Note:- We are working on the entire Graph Algorithms and Geometric Algorithms playlist and It will be uploaded soon.

Bro I really appreciate ur efforts but nowadays these topics are heavily common on youtube and since ur 5 star I guess u must be good with topics like sweep line algorithms and some imp geometric algorithms , topics like dp on trees , SOS dp , things which are less in utube will be very helpful . Its just my personal suggestion. Besides keep up the good work and its my promise if u come up with the topics i mentioned ( the topics most beginners find it difficult) I will be the 1st one to subscribe :smiley:

I would love if you cover XOR basis in algebra, there is very limited resource for learning this concept

That’s a good idea, I will think of that.

We are working on geometric algorithms too. I hope It will be available in few days.

Bro it will be good if you cover those topic which are not available fully in google Or their proper explanation are not given on google .
Like XOR, bit manipulation, and other
These are topics in which most of us are confused

We have got so many suggestions for topics and We will be trying to cover as many topics as we can step by step. Hope you get your topics covered soon.
