A practice Problem solved should be marked as solved in all the Play-lists it is part of.
Currently, it is not showing as solved in some Play-lists (Contest LP1TO205, 1* → 2* etc)
Example (Problem “Chocolate Monger”):
Direct link: CM164364 Problem - CodeChef
It’s link through Play-List: CodeChef: Practical coding for everyone
As it is not marked as solved, I copied code from my submission at direct-link problem, and pasted to Play-List linked problem.
