Hello, Codeforces community

The Club of Programmers, IIT BHU is excited to announce the launch of Graph Theory playlist of COPS YouTube channel.

The playlist contains some basic and intermediate concepts of graph theory. The videos and the corresponding document not only provide explanation to the concept but also provide a proper roadmap on how to study these concepts along with the practice problems.

The videos are in a mix of Hindi and English.

Graph Theory Playlist link : https://www.youtube.com/playlist?list=PLLt4yMoVgczV8N1LTzA6eXoWlXU9MTQv7

Following topics are covered in the playlist:

• Basic graph theory (Terminologies, dfs and bfs)

• Dijkstra algorithm: Single source shortest path algorithm

• Other Shortest Path Algorithms (Bellman Ford and Floyd Warshall)

• Introduction to trees and subtree queries

• Disjoint Set Union (Basics)

• Minimum Spanning Tree — Kruskal's Algorithm

• Minimum Spanning Tree — Prims's Algorithm

• Topological Sort and Strongly Connected Components

.. and we will also be covering some advanced concepts of graph theory soon. Before that, stay updated for upcoming dynamic programming playlist and do subscribe to our channel.

Hello, Codeforces community

The Club of Programmers, IIT BHU is excited to announce the completion of beginners playlist of COPS YouTube channel.

The content is made for beginners to enable them to kickstart their journey in the field of competitive programming. The videos and the corresponding document not only provide explanation to the concept but also provide a proper roadmap on how to study these concepts along with the practice problems.

Youtube Channel link : https://www.youtube.com/channel/UC01TZlNfu29QgG4FmUqVsdg/featured?view_as=subscriber

I am also providing the concept wise link to the videos for the beginners-

• Array, vector and pair

• STL String

• Time and space complexity

• Recursion and binary exponentiation

• Binary search

• Sorting

• Some basic techniques (two pointer, sliding window algorithm, prefix sum technique)

• Greedy approach

• Basic Number Theory (gcd, lcm, modular multiplicative inverse)

• Prime number and Sieve of Eratostenes

• Stacks, queue and deque

• Next greater element and next smaller element

• Sets, multisets and maps

• Binary operators, bitmasking and its application (Generating all permutation of an array)

• Basic graph theory (Terminologies, dfs and bfs)

... and we will also be covering intermediate topics like dp and graphs very soon. So stay tuned and do subscribe to our channel.

The videos are in a mix of Hindi and English
