This blog is perhaps complete nonsense because becoming faster is perhaps equal to generally becoming better at competitive programming. I've found that many hard problems are approachable if given a longer time and that it is possible to get a decent ranking (perhaps ranked 5-15, since I am not that fast I cant) in many contests for just being fast. Solving problems faster also mean more time to spend on the problems few contestants solves.
So, how can I get faster? I believe the general answer will be "solve more problems" or "Practice more", but can anyone give some more concrete clue?
Sorry for posting this nonsense blog.
