Hello again Codeforces!

Two weeks ago we held the first round of VNOI Cup 2024! We hope that everyone who joined the contest had a great time and enjoyed our problems!

On Sunday, June 16, at 21:00 GMT+7 , we will hold the mirror contest of the VNOI Cup Qualification Round 2, and we would like to invite you to join the contest. Remember, if you are a Vietnamese national, consider joining the official round.

VNOI Cup is a Competitive Programming competition hosted by VNOI (Vietnam Olympiads in Informatics community), a group of Vietnamese programmers like you, working together to make programming competitions more fun and challenging in Vietnam. We're a non-profit organization dedicated to supporting the growth of competitive programming in Vietnam. This competition is one of the many ways we aim to achieve this goal!

Again, a big shoutout to our awesome problem setters and testers! Thanks to their hard work, we have an exciting contest ready for you.

xuanquang1999, atoiz, vinfat, JettyOller, Lihwy, BJoozz, darkkcyan, TrungNotChung, lanhf, MofK, Kuroni, Lomk for making the problems!
errorgorn, DylanSmith, McPqndq, awoo, ToxicPie9, shash4321, Savior-of-Cross, KIRIJIJI, Fanarill, g237182, soup, and Optoed for testing and providing value feedback!

The contest will feature 7 problems to be solved in 180 minutes. Points for problems increase with difficulty. Each problem may consist of multiple subtasks, and you only earn points for a subtask if you pass all test cases for that subtask. Penalty points are calculated as the time of the last scoring submission plus 5 minutes for each incorrect submission. Contestants are ranked by total points, with ties broken by ascending penalty points.

Remember, the second mirror contest starts on Sunday, June 16, at 21:00 GMT+7. The official contest will start 1 hour sooner, at 20:00 GMT+7.
