The http://www.codechef.com/ definitely provides amazing editorials for all of their contests, be it their 10-day long challenge or two and a half hour short contest. The editorial clearly mentions the level of difficulty of the problem, the pre-requirements of algorithms and then goes on to explain every aspect of the problem thoroughly. Do have a look at any of their set here: http://www.codechef.com/wiki/editorials-codechef-contest-problems.

I know many will gonna support codechef(as of great community and total indian support) or Codeforces (due to fact that every russian in on that site) but i will say that the UI and statistics delivered by http://hackerrank.com/ is too made on him on the list. The Faces behind hackerrank working over it and making it better day by day for the sake of great, good and easy Editorial and User expireience. So i voted for http://hackerrank.com/.
