Graph Algorithms #1 - Topic Stream

ِYou. can watch all the topic streams in this playlist:

Since this is the first stream on Graphs, we’ll start with the basics. However, we’ll also cover some challenging problems towards the end. If you’re more interested in advanced topics, feel free to join us during the second hour of the stream. You don’t need any prerequisites to understand everything we’ll cover. Here’s what we’ll go over in this session:

• What is a Graph?
• Types of Graphs
• How to store a graph in a computer
• Checking if a graph is connected

0:00 Intro
4:56 What is a Graph - Some introductory definitions
33:35 How to store a Graph
1:02:55 Connectivity in a Graph and DFS
1:29:13 1400 Difficulty CF problem

solved the question on my own. felt so good.

[ShravanKumar-sm]

Please make the whole course on cp. Your videos are really good.

[imran]

This stream was so so helpful. It was awesome. Thank you for you amaizing dedication. Keep up the great work please.

[paulinvitu]

This topic streams are insanely helpful :) It would also be very great if you could leave some other codeforces problems in the end of the stream for practicing afterwards

[anhkhoiaoduy]

really helpful, thanks Shayan, I follow you from Codeforce to now forever

[anshulwarade]

Enjoyed this one, eagerly waiting for next ones 🤩.

[abhilashasupriya]

Thank you Shayan! Please also cover Number Theory in later streams:)

[ArtyomDzagaryan]

Thanks a lot i hope u will do more this topic basic algoritm ❤

[ИванИванова-ля]

Thanks for the discussion. I hope u'll talk about mods theory sooner

[PraveenKumar-mijr]

shayan, can u increase the frequency of your educational streams, because they are so much good, your content is very very good. i have to wait 6 days to watch your next stream. i have watched all your streams till now.

[HasithAddanki]

really helpful, can you show a better code version in the upcoming streams, i always find it difficult to write a clean code

[rajsarkar]

I know C programming, I was watching and you have been teaching in C++ SO my question is that i understand many things but like vectors, pre built functions i dont understand how they worlk and what they do do i need to learn c++? and yes i even dont know OOP. I am excited to learn from you because you are teaching from very beginning i hope you do to all other videos as well. Thankyou sir.

please upload all the slides as a google drive link it would be much helpful for us!

[gayatrikanojia]

Please teach till DSU on trees and centroid decomposition path problems. I also earlier requested you to teach DsU on tree. There are no good resources out there

[pantherwolfbioz]

Can you tell the usual situations where graphs are used to model the problem(in codeforces context, not real life like instagram), sometimes it is hard to see a problem as a graph problem. I think it is more useful. Otherwise I find the stream well done. Thanks.

[mayurpatil]

I find it difficult to visualize graph.

YOU SHOULD START COURSES FOR CP FROM PUPIL TO CM FOR CHEACP I BET I MANY PEOPLE WII BUY IT(AROUND 75$ FOR 4-5 MONTHS) LIVE OR RECORDING ANYTHING WILL BE FINE, YOU ARE TALENTED AND HIGHER RATED THAN ANY INDIAN GM, MOST OF PPL WHO SELL COURSES IN INDIA ARE SHIT AT CP
