I think this thing has gone unnoticed by many . One person pointed it out but the thread got lost .
I want to point out that CodeChef Certified Data Structure & Algorithms Programme (CCDSAP) has a prepare section in which codechef has provided preparation links to learn concepts and practice problems . It will be of great help to everyone starting new and also those who want to hone their skills .
It also has advanced and expert sections too each with their own useful links to learn and practice . It will be a lot of help for a lot of us .
