Don't make a mistake by picking a topic and practicing a lot of problems in it. You also need to practice a lot of problems randomly without knowing the topic beforehand. If you already know that the problem should be solved by using Graphs then you will think in that direction only. So need to practice random questions also. This is a mistake I made.

[@Errichto]

That's true!

[@introduction3376]

Right on man!

[@dhananjaydeshmukh3469]

Before you go random, get the basics right. Solve a lot of problems in graphs if you have to. But rather than solving the problem, understand the problem. Later on it doesn't matter whether you solve the random problem or not. It will be far easy

[@charan775]

@@dhananjaydeshmukh3469 trust me it won't be easy to decipher a given problem into graph or dp or greedy etc. When you solve tougher problems it becomes really difficult. So instead of solving topic-wise better to solve randomly. And if you encounter a new topic then read about it from diff resources solve some problems on it and continue this process

[@dhananjaydeshmukh3469]

@@charan775 that's true, but that only works if you know the basics and you have to solve the already solved problems to get a hang of it. That way random problems becomes harder to solve, at the least. But if you don't even grasp the concept of why. Then all those randome problems are like impossible stuff. To reach the problem of graph, I m sure a lot of people will get confused at recurring concept.

[@kinansaad980]

Hey Errichto, Great video for beginning in CP, for me I know a lot of algorithms and also I'm Expert on codeforces and a five star on codechef but I'm lost or like stuck or something, I started in CP by solving problems and learning from the editorial how to solve them, but no academic background also I don't know everything about the algorithms that I know, I just know how to use them. My goal is to be a lot better, so I'm thinking about getting back to basics and read "introduction to algorithms" book and relearn everything in more details. do recommend this step for me or you have something better in mind?

[@Errichto]

Solve problems, read articles and tutorials, that's enough, really. Books aren't important even if you want to reach very high level. If you want, you can read "introduction to algo" but only if you have good math background, otherwise it's too hard and complicated. And it's quite outdated (at least for CP).

[@kinansaad980]

@@Errichto thanks a lot this will change my plans. my math background is really weak because in school we learned nothing and I really regret those 12 years. last request, do have a good resource for math, like just to get my math background more stronger. math is the hardest thing for me in CP I tried to be good at it by solving problems but that didn't go really well, thanks in advanced

[@Errichto]

Sure thing. Just remember that algoexpert prepares you for coding interviews, not for cp.

[@AmanSharma-hi3fd]

Just my two cents, never pay for any such Interview prep or algorithms courses. There are already plenty of cp and Interview prep study material available freely. Like 6006 by MIT OCW, Leetcode and IB for interview prep, CF and Codechef for CP, cp-algorithms.com for all adv ds and algo.

[@Errichto]

@@AmanSharma-hi3fd It's about valuing your time and choosing the best possible resource. I don't think that LC and IB are perfect for interview prep, and neither is Codechef for CP. My personal opinion is that algoexpert is currently best video-based platform for interviews (but not necessarily the best interviews platform in general).

Using these sites actually works great for beginners too. I stumbled across competitive programming thanks to the book “learn to code by solving problems” and my coding ability has improved immensely within just a few weeks. I don’t like the way that some of the questions are written, but aside from that, it’s great practice. Working on curated list of problems is the key though. If you are just unleashed on random easy problems as a beginner, you will struggle.

I can tell you from experience, that _in companies (!)_ *competetive programmers are the worst* they're *ego-driven*, selfish, not willing to share information in order to outshine others, in order to get confidence boost from their superiors / enslavers *being* specialized in a field / *intelligent isn't worth shit, if your character is shit* it's not against errichto (1st time watching him).

[@oled4503]

​@Dossieri wouldn't say "naught" - cuz it's a strong, but ofc legit statement. is part of that an expression for "one self can't free oneself from the ego" ? if so i'd agree to that part. what i was trying to communicate is that one has a choice - at least sometimes - to make a conscious decision to not let the ego take over all the time in the realm of dualism in order to take care of balance. appreciate ur comment^^

Guys I've completed python basics recently. I've been thinking of trying competitive programming But before that should I learn data structures and algorithms or can I start without it?

Probably best to try and learn some theory as it can help you understand what's actually going on in the program. Start with arrays as they're used all the time then move on to stacks and queues (different data structures)

[@waldenwasted2665]

If you don't know anything about algorithms and data structures you can't solve more difficult problems that require some time or memory efficiency, in my opinion.

[@UnicycleSoul]

@@waldenwasted2665 I know you probably added the "in my opinion" part as to not offend anyone, but it really isn't needed. Facts are facts and knowing no algo/data structures makes it damn near impossible to solve those problems unless one is so incredibly bright that they'll figure out these concepts while solving the problem.
