How bad luck I have! I was going to submit my code, which nearly took 30 minutes for Codeforces Round 943 (Div. 3) by [user:FBI]and [user: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, FB[user:FBI]I and Sas[user:SashaT9]
