Is there a way to sort the Codeforces Problem Set to show only problems from Div2, sorted by number of users solved? Now it shows both Div1 and Div2 when we sort acc. to no. of users solved.

Thanks.

Hi, I was trying to solve 352C - Jeff and Rounding. My solution is 6873811. It's giving output as '0.000' in CF, even in Ideone.com, But in CodeBlocks IDE, it's giving correct answer '0.250'. Please help. What is the problem?

Hello,

This is my first post at CF. So please be polite to me :)

I wanted to seek some advice with respect to practicing. I know that there are many Quora questions posted related to practice, lot of questions in TopCoder/Codeforces forums but please hear me out.

I've been doing competitive programming (seriously) since past 1 year. But the thing is that I don't see much improvement in myself. There are many people whom I know, who started much later than me (like 5-6 months after me) and much better than me now. I understand practice is the only way to improve but I really think it has got something to do with my approach/methodology. It would be really kind of you if you can tell me what's the correct way to practice. Some info : In TC, I can solve Div2 500 in about ~250 during practice. In CF, I'm able to do only Div2 A, B. Some of the questions — if I'm not able to understand how to start, I generally read editorial within some 30 mins. Is this too early? Considering my level, what would be the ideal thing to do?

Thanks a lot for having the patience to read this. You're awesome.
