Finishing CodeForces Round #479 in Exactly 1 Hour

Hi guys!

It's day 20 of quarantine and, out of boredom, I decided to record one of my training sessions in preparation for the ICPC World Finals 2020. Since this is my first time doing this, I decided to try out an easy problem set (i.e. codeforces round #479).

Code with me and have fun!
