By Medeali, history, 15 months ago, In English

I am gray coder and i just solved a div 1 A problem with 1600 rating.I just started competitive programming amonth now and i solved the problem in about 2 hours.Do you think this is an improvement sign or not here's the problem by the way. https://codeforces.net/contest/559/problem/A if you look at the editorial the solution is trivial but it was hard for me to think about it.

Firstly it's not a div2A problem, it's a div1A problem. So I would suggest to edit the unintentional clickbait title.

Secondly, I think solving a 1600 entirely by yourself in any amount of time is a good signal. Because if you are able to solve it, that means you have the thinking level of writing out a solution to a problem of that rating. It's just a matter of practice then to improve the time.

Just had to find the area, too easy. If this would have been asked recently, it would at max be a 1000. No need to brag about it.

    It wouldn't be 1000. And ye spending 52mins on 1795B and having the right idea on this right away. seems legit

Judjing from my expirience it's a sign of improvement. However I would suggest you to solve problems which have been released no more than 3 years ago.

firstly , the problem is old so Im not sure how much it reflects your level on current cf meta but none the less it is good that you solved a 1600 problem. secondly you can see if your level is good/bad by your performances on contests , it is a pretty accurate measurement in long term. So no need to try figuring out or ask it to someone

I went through actually solving this problem, and from what I feel, 1600 is a bit high for this problem. Div 1A is pretty much equal to Div 2C and 2C on average is around 1200 to 1600; I'd say this problem is about average for 2C and feels more like 1400. That said, it's still very good you can solve this even if it takes a long time; with further practice you will be able to figure problems at this difficulty more consistently.
