HURRAY

Wow this was really amazing for me for the past one year i was trying to get into competitive programming but wasn't never giving time to it but during this lock down I actually started doing it. I participated in 2-3 contest in this span of time but in every contest wasn't able to solve even the first question but then i saw div 4 at first I thought that it is some of kind of mistake by it was true and here i took the chance and solve my first question I can't tell you about the feeling Oh god it felt so good i wanna thank Mike Mirzayanov for this contest it really boosted my confidence.
