In this class, we will be solving a hard problem on combinatorics involving a bit of generating functions. Solution will be discussed, coded and submitted on the judge.

Combinatorics - Problem Solving - Part 3

Advanced Combinatorics

In this class, we will be solving two easy-medium problems on combinatorics and variations. Solutions will be discussed, coded and submitted on respective judges.

Combinatorics - Problem Solving - Part 2

In this class, we will be solving an easy and a medium problem on combinatorics. Solutions will be discussed and coded and submitted on respective judges.

Combinatorics - Problem Solving - Part 1

In this session, we will be taking up some problems on Tries, binary tries, tries on strings, and some other applications. We will also be implementing and submitting some of the problems on online judge.

Tries - Problem Solving

Basic Data Structures

In this session, we will be talking about tries, what they are, when to use them, and how to implement them in a simple way and a memory efficient way.

Tries

In this session, we will be taking up some easy-medium problems on DSUs, a few varieties. We will also be implementing some of the solutions and submit them on online judge.

DSU Problem Solving

In this session, we will be discussing what DSU is, how to implement it efficiently and the applications of it. We will also be taking one sample problem.

Disjoint Set Union (DSU)

In this class, we will be discussing some problems on Combinatorics and implement the solutions and submit them. We will be discussing the logic and code and any bugs that we come across. In the end we can discuss some general tips and tricks for tackling such problems.

Problem Solving - Combinatorics (Part 2)

Problem Solving - Combinatorics (Part 1)

In this session, we would be discussing the problem "Chef And Reordering" from Codechef's February Lunchtime 2021. (Problem Code - SOLDIERS) We would also be implementing the solution for the same.

Problem - Chef And Reordering | SOLDIERS | February LUNCHTIME 2021

In this class we will be solving some easy-medium problems on combinatorics spanning topics such as inclusion-exclusion, permutation and combinations etc.
