I noticed something: many problems are rated low even though they feel hard, and some are rated high even though they seem easier than lower-rated ones. Can anyone explain why this happens and how the rating system works? For example, sometimes an 1100-rated problem feels harder than a 1300–1500 problem,and so on.

Is it just me, or are there not many contests this May?

Feels kinda empty without the usual weekly Codeforces rush. Hope some rounds pop up soon ,I'm starting to miss the stress lol,also Big thanks to the problem setters ,it's not easy to write nice problems.

Hey everyone,

I found a great tool that helps a lot . it’s called CSVisTool https://csvistool.com/. It shows how many data structures and algorithms work in a really cool and clear way.It makes things clearer and easier to understand.

Hello Community,

I'm from Morocco, and next months we have the MNPC (Moroccan National Programming Contest). This will be my first time participating, and I really want to prepare well for it.

I'd appreciate any advice, tips, or resources that could help me train effectively. Also, I've heard from some people that the style of MNPC problems is a bit different from Codeforces. Can anyone confirm this and maybe explain the differences?

Thanks in advance for your help!
