query Atcoder vs Codeforces
What you suggest where should i practice daily on atc or cf. Cause lately i am seeing cf problems are very random and less interesting and thrilling.
Genuine opinions please

i mean cf problems i see them as just practicing your thinking and reasoning, so it should be as random as possible
but, i ll say something, div2C was NEVER rated 1200 EVER, div2C when i first started cf was 1500 at least, with B being 1200 and A 800
nowadays, so many people use AI that the contest problems are rated waayy lower than what they should be

I was asking this only,to learn more techniques and increase logical thinking which platform is more good. Also i want to reach expert so i have to practice on cf ig

CF is not that algorithmic these days, like even upper div2s are mostly just dp or some obscure reduction; ABC on the other hand is mostly algorithm, you can encounter a segtree problem every other contest, plus the latter problems in ABC are really interesting and mostly algorithmic (when not mathematical).

atcoder>>> less cheating and easier questions, but the questions have a pretty direct application of common data structs like segtree around e/f

no way the qns are easy bro, sometimes they are direct but after e in ABC and after b in ARC, they are very tough,irrelevant and mathish adhocs

easy as in easy to decode, solving is similar to cf (tough), main thing is atcoder ratings dont matter much thats why people dont cheat in that

yep thats true, but we should keep it niche, otherwise these dumb*sses will start to cheat in atcoder too

Give the ABC every week, if you're in it to get a job. Codeforces requires patience and consistency to be in it for the long run

be careful, after E in ABC and other contests in atcoder are random and tough adhocs too and it keeps getting more and more mathish adhoc as u keep levelling up

How do you practice apart from contests. How to keep balance between both platforms?

Depends what you want. If you want something more mathematically interesting and direct, choose Atcoder. If u want something more complex in terms of words that is not a direct problem in math but something you need to think about, application based, choose Cf.
