I invite everyone to the 3rd Contest of the ICO Preparatory Series 2018-19 to be held on Codechef. It is aimed at helping students in their preparation for the International Olympiad of Informatics. The topics can be very important for ICPC as well.
The contest guarantees original problems and fast editorials.
There are 250 laddus for the top 3 Indian school students.
Hope you enjoy the contest and find the problems interesting!
