Hello coders,

probably some of you know CodeChef (another programming contest page).

Why am I writing about another page? Because I believe, that when you want to make your rating higher, you have to compete in contests. Some coders think, that practice and contest are the same (just solving the problems), but definitely they are not for me. In contest I'm under the pressure (time pressure, fear, that if I do not solve the problem my rating will be lower, ...) and so I'm doing a lot of mistakes in real contest (like not reading statement carefully, missing some conditions, trying to submit quickly without precise testing and so on). That's why I want to share with you, that on CodeChef page there are long contests. For me it's something in the middle between practice (no competition, no fun) and competition, because you are not under the time pressure.

But real reason, why I'm writing about CodeChef long contests is, that I worte extension for Chrome, that marks solved problems (what CodeChef page is not doing by default).

There were some extensions discussed in this question, but mine works better.

Description

Extension works for all problem tables. Green tick is for problems solved in contest, orange one is for problems solved in practice.

1.) long contests

2.) short contests

3.) practice

Some minor bugs were fixed in version (problem tables on main page and on user profile page do not have additional header column).

New feature in version is, that problem title contains ticks if you solved the problem already — it is useful if someone has problem on forum, then you quickly know if you solved this problem already or not.
