Basically codechef introduced its pro version as premium just like other coding preparation websites i.e, Leetcode, Interviewbit, etc.
Now Codechef is not free coding website , as we understood the codechef team working and efforts to make it best coding platform .
Its IDE is also introduced as new version that keeps interactive more than its previous version.
So, we coders can only support codechef and would like to propose its premium version can be provided as awards and prizes in the live contests to participants.
