Hi Codeforces,

I recently came across this wonderful post by chromate00, in which he introduces a game similar to GeoGuessr in which you are supposed to guess the data structure used by random cheaters in a Div2 contest. This satirical blog post led to me brainstorming about a game idea for a few days. I don't really have a name for it yet but I am thinking of a name like GuessrForces, CPGuessr, AlgoGuessr, PatternFindr, PatternGuessr or something similar. I want to briefly introduce the main idea here so let me know what you think of it and comment if you have anything to add!

The main idea

The main idea is to build a website similar to GeoGuessr where you are presented a problem statement and the input constraints instead of a random location. You are then given some amount x of time, with x increasing/decreasing based on your rank, after which your task is to find the correct pattern/algorithm/data structure that is used in the solution of the given problem. You should ideally also provide some kind of explanation describing why your chosen pattern/algorithm/data structure is the correct one and how you recognized it. The text you are given might not always contain the full problem statement, it might also merely be relevant snippets or it might be purposely big so that you also learn to abstract away unimportant details while focusing on the important bits and pieces.
