FB Page | Info |

Steven Halim and I recently published the Competitive Programming book which is targetted to help regular computer science students to quickly get up and running for the ACM ICPC as well as IOI. The book discusses the types of problems that are frequently occurs in programming contests. The exercises have been integrated to this uHunt tool so that you can keep track of your progress. To get started, select a chapter from the table on the right and happy solving :)

Next Problems to Solve

You can view your unsolved/solved problems, sort them, filter by volume, etc. If you just want to solve as many problems as quickly as possible, it's convinient to pick problems according to the dacu (distinct accepted users) in descending order. The bigger the dacu the easier the problem should be and the more probable it will appear in the UVa discussion board.
