I made two videos for people who are newbies right now. I said everything I tell my students to grow and get out of newbie. These are the things that I did myself as well, and around 4 months after being a newbie, I got rank 4 in a div 2 contest. This is the first video on this topic. I highly encourage you to do these things if you are a Newbie right now!

Things you must not do if you are a Newbie:

If you like these kinds of videos, let me know what helps you the most, and I’ll try to make more videos on those topics next.

Tomorrow, we’re going to solve some super cool problems from graph algorithms. I’ve chosen some of the best problems, ranging in difficulty, and some are really challenging and beautiful. However, you don’t need any prior knowledge to solve them besides what we discussed in the previous two topic streams on graphs, so anyone at any level can follow along.

Don’t miss this topic stream! I look forward to seeing you all tomorrow!

I highly encourage you to watch the previous two topic streams on graphs at 2x speed to ensure you’re comfortable with all the topics!

Let me know your thoughts!

This stream has to be moved to Saturday. Sorry about that.

Since you mentioned Atcoder beginner round, I will stream the solution discussion of ABC round 370 tomorrow and do the topic stream on Graph problem-solving the day after that. (Sunday)

We’re having our “Graph Algorithms Problem Solving” session tomorrow! (Sunday 14 - 16 GMT) As the title suggests, it’s going to be from starter to expert! I’ve picked the best problems that require no prior knowledge—it’s all about the ideas. I’m excited because I’m sure you’ll learn a lot about the art of problem-solving in this stream!

P.S.: If you have any suggestions for the thumbnail, let me know! xd

As you might know, ICPC is happening in a week! Based on your suggestions, I’ve created an Instagram channel to share more content there. I’ll be posting a lot of interesting things, and I hope you’ll enjoy it!

PS: There’s already something cool there that I haven’t mentioned anywhere else yet. Can you guess what it is?

From winning a gold medal in the IOI to earning over half a million dollars a year, I’m interviewing someone who learned to code before he could read.

Arash’s story is incredible. Born in Iran, he grew up writing programs. He studied Olympiad in Informatics during high school (where I first met him) and went on to win a gold medal in the IOI. Later, he moved to Canada to pursue his bachelor’s degree at the University of Waterloo. After gaining experience and completing a few internships, Arash moved to the Netherlands to work for Radix. Now, he’s waiting for his visa to relocate to the US.

In this interview, Arash shares his thoughts on IOI and competitive programming, how he prepared, and his journey to becoming a quantitative researcher and landing a job in the field.

This is my interview with Arash Mahmoudian, one of the greatest competitive programmers who is now working as a quantitive researcher.

Especially, if you have questions about finding a well-paid job after learning competitive programming, this is an interview that you should not miss!

Here is the Codeforces post of this interview:
