Hello CodeForces,

I am facing some problems about modular arithmetic and i am asking you guys, if you can suggest me some resources from where i can learn it. Thanks in advance!

I know that this question is not maybe for this site but i do not have better option to ask a widely community.

Hello everyone,

I hope you are good. I have been struggling with time complexity and it always worries me will i get TLE. I hope that you have some articles, blogs or whatever resource to share it to me, i would be grateful. Thanks in advance guys!

P.S. If you have some suggestions for MLE, write them down below in the comments.

Hello Codeforces!

Graphs are not really my thing, and i want to learn them so i can solve some advanced graph problems. Like problems (theory about them also) where i need to implement algorithms such as DFS, BFS, Djikstra, cycles, Floyd — Warshall, Bellman — Ford, trees etc... If you have some resources from where to learn, I would be grateful if you could share it.

Hello everyone!

Recently i have been struggling to find the best way of solving complex problems as I try to improve my problem-solving abilities. Any advice or strategies that could help me realize and solve problems faster will be highly appreciated. Thank you very much in advance!
