Hello Codeforces! ↵

Back from the dead, we'd like to invite you to the [online mirror](https://codeforces.net/contest/1970) of the Helvetic Coding Contest, Switzerland open championship! You can find past mirror from [2019](https://codeforces.net/contest/1184), [2018](https://codeforces.net/contest/958), [2017](https://codeforces.net/contest/802), and [2016](https://codeforces.net/contest/690).↵

The [Helvetic Coding Contest](https://polympiads.ch/HC2/) used to be held yearly at [EPFL](https://www.epfl.ch/en/). This year, the [Polympiads](https://polympiads.ch) association is bringing it back alive! The contest itself took place on April the 13th, but the online mirror is scheduled on Saturday, [4th of May, 09:05 Swiss time](https://www.timeanddate.com/worldclock/fixedtime.html?day=4&month=5&year=2024&hour=10&min=5&sec=0&p1=166). The duration is 4:30.↵
↵
Rules:↵
↵
- you can participate in teams or individually with a single computer (1-3 people),↵
↵
- standard ACM-ICPC rules (no hacking),↵
↵
- the contest is not rated,↵
↵
- if you have participated in the onsite contest, please do not participate in the mirror.↵
↵
Contrary to what the mirror's date might lead you to believe, this year's theme is Harry Potter. It features 7 series of 3 related tasks with increasing difficulty (easy/medium/hard). Note that we do not guarantee that all problems are solvable using python. ↵
