CodeChef INOI Workshops 2019

About the workshop:

These workshops are aimed to help the school students who are preparing for INOI. They are organized by the volunteers from the CodeChef community with the support from CodeChef.

INOI is the national round of the Indian Computing Olympiad conducted by IARCS to select 25-30 students for the next level, i.e. the training camp. Out of these camp students, finally 4 students will be selected, who will represent India at the International Olympiad in Informatics 2019 at Baku, Azerbaijan. For reference here are past years INOI problems.
