Hello, Codeforces!
We start a new season of the Coding Club! This year, things will be different from the last one. Every week, livlivi and I will post a short lecture and a themed contest. Then you will have one week to solve it. If you have any troubles, we will have several teaching assistants, who will help you personally.

The plan for this season is to cover these topics (not sure if we will have enough time, but we will try):
- Core techniques (prefix sums, binary search)
- Dynamic programming
- Graph algorithms (DFS, BFS, MST, shortest paths)
- Data structures (stacks, queues, DSU, segment trees)
- Tree algorithms (DP on tees, LCA)
- String algorithms (tries, KMP, hashing, Aho–Corasick)
The club is starting this week! If you are interested, register here. See you!








Is there any criteria for student's other than high-schoolers(Enrolled in University) ?
Hi! Youth Club is targeted for school students, however you're welcome to join and solve problems as well. ;) Please note that we cannot guarantee personal support from teaching assistants for non-schoolers. See you at our Club!

finally changed ur pfp, not claude any more
this pfp is so fucking cringe so people will automatically know i am a troll and wont bother taking my words seriously.
so basically i changed my pfp for other's protection
still from artificial intelligence lol
DP on "tees" or "trees"?
tree
so people who are saying "tees" or something like this can you please just ignore it?
the mentors here can solve problems, understand topics better than you, plus cmon bro just type error who cares about this.
Great! i just hope I can learn more about these things and make some new friends along the way. btw, anyone want to practice with me ? We can chat, share ideas, or maybe even have discussions over video calls.
this is great
I remember the live sessions are difficult to join due to time zone, will you share recording later?
Can University students join if in the age-range?
Will it too expensive?...I'm Interesting but afraid of my wallet
It's free
I want to invite my friends to this hobby, will this be a good enough resource even if they have no programming language knowledge?
EDIT:
Chinese Oiers,CSP-J/S 2026 will come in 2 days , hope you all RP+=INF!!!!!!!!!!!
whats csp-j/s?
It's a Chinese programming competition,1 time per years , it can help for get into a better high school or college because it's useful for oiers.
where to access the problem (i js wanna upsolve for fun)
Should it be "DP on trees" instead of "DP on tees"?
Should it be "Roottree" instead of "Rootree"?
