In my experience, programmers generally recommend SPOJ when it comes to training. But is there really a difference, b/w Codeforces ProblemSet And SPOJ ProblemSet? If yes, then how? What would you recommend?
P.S. — My Aim is to get good at Codeforces. I am currently feeling pretty stupid, often stuck on Div2. C/D.
Pretty simple, if you want to get better at Codeforces, you should practice more Codeforces problems. If you want to get better at Div 2 C/D, you should practice more Div 2 C/D problems.
Yes, you are correct. We need to solve more problems on Codeforces if we want to be good at Codeforces.
The question bit_2 should be asking is "Which platform should be followed to perform well at ICPC/GCJ/FCH?"
