        Says what, kid? Explain to me wtf is this submission. Adding some nonsense functions and using wierd variables can not hide the fact that you are an amatuer cheater. You cheated in every recent contests, a fucking noob cheater giving advice to others on how to get better? That's the most hilarious shit I've seen in my life.

            Yeah, with that naive thinking, no wonder why you are green. If only you could use your brain a little, you could have reached cyan easily.

            First, that guy had been skipped before, that claims he once was a cheater. Second, he has unsual good performance, just last three months he still struggling doing div 3-4 but now he's solving div2 like it's nothing to him, Obviously he's still cheating. Third, regarding of the submission in which I claimed he cheated, not only he uses stupid variables, he add some weird math caculations there (who the f adding something like 10-10,5-10,10-9 in their code during the contest LOL unless they're trying to bypass the system),

Particularly DFS/BFS, bin search, dp, data structures, greedy and of course math. It is obvious that math here is the most important.

You can do some DP problems,and you need to improve your math skill too.

Topics: Basic data structure, greedy, binary search. When I became expert I also knew BFS+DFS.

Biggest tip I can give you: Practive div2 ABCs. Work on your speed & accuracy.

Check out the CP-31 sheet by Priyansh31dec. It contains some of the most beautiful problems on important patterns which might help a lot in reaching expert.
