The practice section of Codechef has lots of problems, specially "easy" ones. So the people who want to practice problems, find it hard to keep track of which problems he/she has solved, and which he/she failed on.
Wouldn't it be nice to have some way to distinguish between "solved", "wrong-answer", "TLE" and "not-attempted" problems for each user inside practice section?
Like there can be a column to show green-tick for solved problems, or the entire row background can be made green.
This will motivate new users to solve more practice problems.
