At 2:20:50, "I am one problem short of tourist guys, can't really complain here" .. awesome SecondThread 😀 🌟🌟🌟

for Problem: C--> each element ai in the array a 1<= a<= 10^9 so no need to worry about zeros. Still this is a great addition to the problem.

[PegasiuuuS]

One suggestion, would you please put the pen paper on the bigger screen and facecam on the smaller one

[rohankhatua]

Hey, while writing solutions on paper could you make that full screen? It would be much easier to see, thanks.

Can the problem D be solved using simulated annealing method?

[Aditya-ifij]

I'm not even able to do A in last few contests 😵

[NikhilKumar-xpjd]

@SecondThread While writing solutions on paper, it will be very helpful if that can be bring up on the screen.

1:33:57 Second already knows how infested Codeforces is with alternatives and double accounts but decides to act like he is actually legit impressed 😅. Second my guy you and I both know that if you are not in the top 5% coders the elo of codeforces has been broken so badly with bots and alts (aka smurf accounts) that you can't show up higher than blue if you are not in the top 5% (in reality). Well they could fix this by introducing 2 rating systems one will show your verified profile rating and the other the unverified one. How do you verify yourself you might ask? Well just provide a physical address and pay $5 to Codeforces to send you a mail that contains a verification code. I mean it is just that easy to have legit ratings introduced but the guys at Codeforces won't do that because they themselves are in the top 5%. So I suggest to anyone to stop caring about the ratings and just use Codeforces for practicing.
