I reached 1500 in Luogu recently. How is this score in Codeforces? How can I improve my thinking level? And how diffuclt problems should I do? Should I do 1600~1800 in Codeforces and green in Luogu?
For all Chinese, I wish you perform better in the CSP Round.
For all foreigners, I wish you perform better next CF Round.
Downvoted.
Downvoted.
So how can I improve my skill?
First, it's sure an achievement in your programming. To improve yourself, you can do some green problems just as what you think.
You should post it on your Luogu instead of CF.
Edit: Sorry. I've missed some part of the blog. :(
