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!
