What ENGLISH-language free online arvchives (with online-judges) with VERY EASY problems can you propose? Level of problems should be NOT for olympiads at all, but for very beginning of programming; the desired difficulty level is smth like (Russian-language) http://informatics.mccme.ru/mod/statements/view.php?id=276 (exercises to use if statement) or http://informatics.mccme.ru/mod/statements/view.php?id=208 (exercises to use 1D array).

If OJ contains both hard and easy problems, it's REQUIRED that easy problems are already selected to clear separate lists. The situation like as "anyone can try a lot of problems and choose easy among them" is NOT what is required.

It's not for olimpiads training, it's for teaching very beginning of programming. There should be at least tens (or, better, hundreds) exercises of such level as "is year leap", "count arithmetic average of given numbers", and so on.

The problem is that some harder problems have many successful submissions because they were previously the easiest problems in Easy Section (since Beginner Section was introduced later).

 » 6 years ago, # | ← Rev. 2 →   +2 UVA Online Judge has some easy problems. To distinguish them, use UHunt, which is an extra tool that is present in the menú. This page is the companion site to Competitive Programming, so UHunt has the problems categorized even by topic. (Chapter 1 has the problems you require)
