Problem E: AC & WA.

Problem B: AC & WA. I forgot to put an else after the if, but I still don't know how it passed the samples.

Problem C: AC & WA. I forgot to check whether L > R. (Actually, I could've fixed this with a few small modifications to the code, but I didn't want to risk it because my brain cells were already cooked after Problem B.)

Also, since I was in an uncomfortable and noisy environment, I couldn't figure out how to solve problem D in time and solved problem A in 11 mins (as an Expert it's a shame)
In conclusion: Never, ever try to participate in a contest in an uncomfortable environment or You'll be cooked like me
Personal Thoughts: To be honest, I really enjoyed the problems, even though I ended up with a negative delta.
Thanks to the authors for organizing such a great contest: conqueror_of_tourist,TheOneYouWant,FlakeLCR,applepi216 orz








nt dude, the fact you tried is enough <3
Thanks for the kind words. I'll make sure to come back stronger in the next Div. 2
thats the spirit!
I think if you plan to do onsite contests, it's sometimes good to participate in an uncomfortable environments online. Eventually you might have not very nice environment on onsite contests, those online contests would help a lot.
