About

Contest

The Northwestern Europe Regional Contest (NWERC) is a contest in which teams of three students from universities all over northwestern Europe tackle a series of algorithmic problems. The goal of each team is to solve as many problems as possible within the 5-hour time limit. Teams submit their potential solutions to a judging system where they are automatically evaluated.

The problem set consists of a number of problems (usually 12) and will be provided in English at the beginning of the contest. For each problem, teams are required to write a program in C, C++, Java, Python, or Kotlin that reads from standard input (stdin) and writes to standard output (stdout), unless otherwise stated.

The team that solves the most problems correctly wins. If two teams solve the same number of problems, the one with the lowest total time is ranked higher. The total time is calculated as the sum of the time taken for each solved problem, with a 20-minute penalty added for each incorrect submission.
