Hi all,↵
↵
Using some code, I made a compilation of some past problems along with the solution to the problems. [Here](https://drive.google.com/drive/folders/1bgX2p4vzmSYaSu5hbRhQ5zpaSY4yJgv8?usp=drive_link) is a link to the resulting book.↵
↵
The inspiration for this book came from chess puzzle books. There are a few versions of this: one with just the links to the problems, one with the problem statements (but no solutions), and one that also includes solutions. Much of the motivation in using code from [user:jiangly's,2024-01-07] submission is the brevity and cleanliness of the code, though being a member of the fanclub certainly contributed.↵
↵
The book is currently on version 1. Some features it's missing include:↵
1. Written commentary about the concepts, meta points about practice, and other tips.↵
2. Comment on the code submissions.↵
↵
**How should you use this book**: I would choose a topic near your color and start solving problems, probably spending <1h per problem. If you have trouble understanding a submission, the editorial probably helps, and a tool like GPT might too. You can also try to break a problem down into two parts, coming up with the idea & implementation, and practice them separately.↵
↵
It will probably be a while before I remember the concepts well enough to add comments / guides about them, since I haven't played much cf for 2 years. I may not work on this more. If you are interested in contributing some writings for it, let me know.↵
↵
The problems are written by Codeforces writers, and all submissions are from jiangly. I believe this follows the [Codeforces copyright rules](https://codeforces.com/blog/entry/967), but if there are any concerns please lmk.↵
↵
Happy problem solving!↵
