Can I see if my solution to a contest problem is correct after the contest has finished?

When the contest is over, editorials for problems are published here in forum, you can find them here by tag - Topics tagged editorial and typically editorial links to tester and setter solution.

Contest problems are normally added to the practice section shortly after the contest is concluded, and you can submit them there. The fastest way to get to the practice problem is to delete the contest ID from the URL.

For example, to submit the problem at CodeChef: Practical coding for everyone, delete the JAN10 and instead go to L3 Problem - CodeChef .
