How to Prepare for the Programming Olympiad?

Question

Algorithms

Hello. In 2 weeks I have to go to the same Olympiad with the guys, but before that I had never gone to them. I really don't know what to expect, what will happen and how. Just out of curiosity, I agreed. But somehow I don’t really want to lose face either ...
I ask knowledgeable people to tell me what to prepare for, what to repeat? Also, if there are short but capacious resources on all the main algorithms, please share, I will be very happy! So that you can just go over your eyes and "remember everything", as they say.
Thank you!

Answer 1

There were articles on Habré, examples of a task, their analysis. Description of how they are carried out, how decisions are checked, how assignments are drawn up, etc.

Solve problems on different topics. Start simple. Practice doing I/O of various data from/to a file. Remember how to work with strings, arrays (including two-dimensional ones). Whole and real numbers.
Read up on graphs (adjacency list, adjacency matrix, traversals, pathfinding).
Most likely there will be 1-2 simple tasks, for "modeling", where you just need to do what they ask.
Dynamic tasks are usually complex and it is difficult to learn how to solve them in 2 weeks, but if you have time, read a couple of reviews.
Often there are tasks on geometry.
