i was wondering if each question code is unique? i hope the question is clear or you can check this list Solve Coding Problems Online - CodeChef and in the code column there’s a unique identifier?
Yes. Problem Codes in Codechef are unique, so the problem links. The link to any problem is given by:
https://www.codechef.com/problems/<PROBLEM_CODE>.
Example:
https://www.codechef.com/problems/REDONE
