CodeChef Long Challenges

About the contest: CodeChef’s Long Challenge is our signature monthly coding contest which spans a duration of 10 days. The coders compete while they improve on their overall programming skills. The 10 days contest duration gives one enough time to efficiently tackle a problem by reading the concepts one doesn’t know, and experiment solving the problem by solving in different ways and thus improve their skills. The contest packs the excitement of coding with the fun of learning into one compelling challenge.

Schedule of the contest: The contest begins on the first Friday of every month at 15:00 hrs IST.
