Orange072's blog

Can you please guide me how can I be better on codeforces? I feel like everyone is really good here.

I just started this journey now. I'm just feeling that I'm really stupid. Others are performing really well on contests. I'm not many times able to pick up the AD-hoc idea for Div-2 B and many times not able to implement it clearly. I often implement it in really complex way which leads to wrong answers on edge cases and other silly small mistakes. And can I aim to become master? Haha I'm daydreaming too much.

    You have solved almost 600 800 level problems. Try stepping up, even if it feels challenging at first. I would recommend 1400 level problems, since you haven solved only 6 of them so far.

        also i think you should switch to cpp? learning STL in cpp might help i guess.

Practise.

I think it's a good idea for you to do the problems with *1000 difficultly.

Please excuse my English.

Hi, I really suggest you just try as many questions as possible, a lot of the concepts are appearing again and again with little changes, I suggest you will look at question from cses or here. I am in a competitive programing team for my country and that's the first thing they tell us, I know my rating is kind of lo because I just started but I hope you will get better and this will help you!

    Thank you so much! today in div 3 contest I was able to solve 3 questions, but I made lot of silly mistakes, and which costs me too much time.

      You have to distinguish if you're having a problem solving issue or a coding issue. If you really solve the problem and make some mistakes while coding, relax because the practice will make you better and better. If it is the other case, maybe (really) solving the problem before coding helps you. For me I think that's the case. I should analyze the problem better before start to code. Good luck for us :)

        I'm able to solve questions but it is taking a very long time and with very messy code. I think I should focus on more implementation problems.

In addition, I really suggest Cses its a great website and the questions really help and are similar to competitions! good luck with improving, you got this!

sorry, I'm talking that much, I was just in a similar situation. if you need help in completing the questions from today's comp, which I really suggest you do, and have a problem with it, write here and I will see if I can help you, you are not daydreaming, everyone starts some day, there are people here with years of experience, of course they will be better, but give it a month or two and if you practice you will see the changes. trust me I was in the same position a year ago! I hope to see you a master soon :)

        im new here and its been a months ig and i'm only able to solve 800 and some of the 900 questions, and i feel im progressing very slowly, and i often think that even im doing right and if im on the right track. What should we do when we are stuck at some point, And another thing that is that enough if i only solve question on codeforces level wise without learning any new concepts from yt but from questions itself

          I would learn data structures as most question above 1000 invlove knowing more complex data structures so that algorithem can run faster wth the terms of the question, good data structers are map, set, segmant tree, and vectors, I would learn about those and their uses, I would als look up some basic algorithm whic are very common, like binary search, two pointers, dfs and bfs on graphs and dixtera, you can go to cses to solve sme question with basic but importent concepts, I suggest to do sorting and searching and dp question!!!

Whatever practice you think you need to get some level, you likely need 10x more.

I totally get it

and it's not even like you're gonna become green or blue and like, NOT come down to newbie again. I've joined the community for around 7 or 8 months now, and many friends of mine have had a better performance in probabbly less time. But the key is, in my opinion, just practicing and have a coding routine. solving problems alone is def good but contests are a whole other realm due to the fact that you know you're risking over ur beloved rating and all the time managment stress... guess that's just how people become good at it. Getting used to failures and believing in the process I guess?

-Btw I didnt mention learning new theoretic concepts cuz I guess that would be most trivial

I have changed my approach 10 times but now my current approach is never look at the editorial even if you couldn't solve the problem just leave it and try the next day

    I think you should read the editorial if you can't solve the problem on the second try or the third try, some problem have smart approach so maybe you cannot solve it with the common approach. Leave the problem if you can't solve it is a good tactic. P/s: my advice mainly base on a practicing tactic of a GM in our country that I tried and improve my skill. It your choice though, it may work for me but not for you.

I think you should focus on doing problem correctly super fast, I learn lots of algorithm (may be enough for me to get to expert, about a quarter of my classmates is higher than expert) but still struggle a lot to get to pupil because it take me at least 5 minutes or more to get to problem B and sometimes even A wrong (but I can do C, D that time) (in div 2, 3).
