Hello Codeforces, By the end of this year I want to get stable blue(expert). How should I practice? Presently I'm fluctuating in green and don't know how to get out of it. Also would practising on other OJs will be beneficial? I'm determined to achieve blue but don't know how to get ahead. Please help
See this.
Hehe but this wasn't the intended purpose for this post
There is no specific roadmap..
What works for some people doesn't always work for everyone else.
no. there are blogs which are specific like this this & this. Googling stuff is an underrated yet very important skill.
I like how the first result is my blog. That is cool!
Should one use more than one OJ?
In my opinion,practicing on multiple OJs would make you a more experienced and better competitive programmer in general,as practice always helps. As far as rating on Codeforces is concerned,in order to achieve higher rating,you need to solve more problems on Codeforces,as Div2 A,B,C problems are more adhoc in nature,as compared to problems on other OJs which are more algorithmic in nature. Once again,this is just my opinion. I myself have a lot to learn and improve..:)
you are unable to be an expert. go find any other hobbies
That isn't something I'm looking for
Learn a programming language.
