2017 Canadian Computing Olympiad Day 1 Mirror

This will be a mirror of the 2017 Canadian Computing Olympiad (CCO 2017), the contest primarily used to select Canada's IOI team. There are 2 separate contests, Day 1 and Day 2. Scoring will follow IOI format with full feedback and partial points but each task will be worth 25 points. For each day, you will be given 4 hours to solve 3 problems. Each day can be started at any time during the contest window.

The problem setters are azneye, Eliden, and FatalEagle.

The rounds will be unrated.

CCO '17 P1 - Vera and Trail Building 7p 39.5% 254
CCO '17 P2 - Cartesian Conquest 20p 6.5% 31
CCO '17 P3 - Vera and Modern Art 30p 9.5% 50

    Very nice contest. Will there be an editorial after the contest? And if so where it will be posted?

    Triggered @ CCO. Eliden's problem is so triggering.
