You will be delighted to know that there are some very nice people who write mini editorials in their codes. Unfortunately I found only one such user — piddddgy . Please mention them if you know more such people. It would be of great help for people like me who don't understand author's code. Thank You for your time.

I want to know your views on "long contests" (eg Codechef Long Contests). Lets keep aside the point that it has less credibility (because of copied codes or googling skills). What I really want to talk about is the time that we spend on a question is way too much. I have been stuck on a problem for last two days and I don't really know whats wrong. It got me thinking that "Am I wasting my time?". Please share your views on this......Thanks for your time
