interactive session

Is it not possible that codechef starts some special interactive session with the editorialists where users can further asks there doubts?

If I understood you well, you have some questions related to contest problems, right? You can always ask here in forum and someone (not necessarily editorialist) will answer your questions. Prefered way is to post your question as an answer (yes, this is weird) to editorial “question”. It’s polite to read previous questions to not to ask same thing again (typically for WA, test your algorithm with test cases published before).

But this holds for “after the contest” stage. During the contest it is restricted by guidelines what you can ask - What kind of comment should I post on the problem page? - help - CodeChef Discuss
