I was going through yesterday's hacks and I found some weird stuff :
For Problem A there was a hack made by adityakr619 on Justadi698
Link Here https://codeforces.me/contest/1976/hacks/1027807
they literally had hardcoded a case which might not be in testcases to be hacked???
as according to the problem this should return a NO
Also in the same contest we had this
Literally all A hacks were similar, Educational rounds don't carry points for hacking right?
