How bad luck I have! I was going to submit my code, which nearly took 30 minutes for Codeforces Round 943 (Div. 3) by FBI and SashaT9, and suddenly, in the last minutes of the contest, the site got so busy that I couldn't submit my code.

Guess Destiny beats Hard work just like in Kung Fu Panda 4.

Well, anyways, the questions were good. It was fun. Thank you, FBI and SashaT9
