The Ultimate Topic List (with Resources, Problems and Templates)
By YouKn0wWho, 8 months ago, In English

This post took $$$4$$$ years to make. And this is the most significant thing that I have ever shared in my whole life.

Story

Hi, I have been doing CP for like $$$4$$$ years and from the very beginning what I have been feeling is a need for a comprehensive topic list that will contain all sorts of topics from easy to advanced with corresponding tutorials, problem lists and templates so that I wouldn't have to look at different sites, from here to there. So what do you do when you think something is missing from the world? Yeah, you create that thing! So here I am, sharing the ultimate topic list that you will need in CP.

When I say that it took me $$$4$$$ years to make it, I genuinely mean it. I have been collecting them from the inception of my CP journey and yesterday I thought that it got its almost complete shape. You may not imagine the sheer excitement hidden under each of the characters of this post.

Payment

You can pay me just by upvoting this blog and by being a better programmer and human being than what you are right now.

About the Topic List

I have added a few tutorials for each topic. You can also find more of them by just using your best companion — Google.

Added few problems for each topic. But you may notice that some of the topics don't have any problem attached. That's because under the attached tutorial section you will find lots of problems with that topic. If you want more problems, then you can do it just by using Google.

I have attached my template for each topic. You may not call it a template because some of them don't support the generalized use of the topic. But you can use them easily if you understand the topic and solve problems using that template.

Lastly, I tried to state the difficulty of each topic by numbers from $$$1$$$ to $$$3$$$ so that people can understand what are the best topics for them. The distribution is as follows:

  • $$$1$$$ — If your rating is $$$1600 - 1899$$$
  • $$$2$$$ — If your rating is $$$1900 - 2399$$$
  • $$$3$$$ — If your rating is $$$2400+$$$

If you are a beginner then just learn basic topics and solve problems.

Contribute

You can comment the topic names that you think are missing right now and I am pretty sure some links are broken, do point those out if you find some.

Additional Comments

I really wanted to post this blog before I die. Seems like I managed to do that. It's funny that I had this constant fear of what if I die before sharing this blog with the world given that the amount of work I have given to create this is monstrous. But now I am so happy that I am alive at this moment.

Conclusion

The whole purpose of this project is to help you with this astounding journey of you trying to be better, trying to achieve the best of what you can imagine. Hope that my efforts won't go in vain. I am waiting to see you at the top of the building that you made by the bricks of your expectations. I am waiting to see you smile and to be happy. Don't forget to enjoy the journey and have fun while riding the boat.

Best wishes, my friend blobheart.

    Well, many of them gathered and or created their library bit by bit and learnt throughout the whole process. For the perfect code sometimes several trials are needed. When you just get a full library you can't actually realize how much effort is needed for that. What Shohag vai did is really amazing. But if he didn't you couldn't blame him for that.

After seeing your post on codeforces, I thought I should have to work harder. Thank you for giving us such a library. The only regret is that you have not now accepted my friend request on facebook.

Amazing contribution brother, but I've one concern.

I'm certainly a beginner to CP so I decided to follow your list completely, I had requested access yesterday morning but haven't received any access updates till now.

Do I have to wait till they provide access or what??

EDIT: It's been two days, I still haven't received any shared access on my Gmail. Can someone help me out??

If it isn't too much of a hassle, could you please put the lists into separate 'spoiler' tabs? i think it would greatly improve navigability! The long lists (for which i am very thankful) are quite tedious to travel..

        I did the appropriate changes for this but when I try to post the blog it shows 504 gateway time-out (I tried 5 times). Maybe that's because the raw HTML file contains almost 200k characters.

          That's a pity.

          But then I think there is no reason to hide everything in one big spoiler. That's the main part of the blog.

          (also, amazing job!)

I also wanted to point out that the link for matrix exponentiation problem is taking me to FTT problem. maybe you put a wrong link there by mistake. It is a little misleading so I would recommend removing that.

Great blog Brother. At first, I thought these are all very advanced topics and I really should not learn new topics, as I already learned and practiced so many algorithms that I never used, or could use/implement, or even need at the level/rank I am currently in. But then again, while scrolling through the blog, some topic names caught my attention, which I could not resist learning. I tried to know more about Matrix Exponentiation, range BIT, and today while solving random problems, I even got the chance to implement range BIT!

(BTW pls suggest to me some more interesting topics from the list, that I will face more frequently in the future)

    That's a bad idea. This is a huge list and many topics are very advanced.

    Practicing CP is about understanding algorithms and applying them yourself, not just about reading an article. It takes time.

You have done a great job sir it will help many CP lovers.

But, no one talks about beginners when we all know beginners get more difficulties in finding proper materials and all. Due to this i am stuck at 1200 since 2 years after doing more than 1800 questions on 'codeforces'. you can feel my pain from every character of this post.

Thanks for the list. Only one problem IMO, a lot of the topics are way too hard relative to the rating that they're assigned. For example, who needs to learn about prefix automation or dinic's algorithm as an expert?
