Hello codeforces

yesterday there was a div4

at the middle of the contest

I noticed that a large amount of coders came up with the solution of problem E at the same time

so (as I am unrated for div4 contest)

I did some search on internet

and found a live stream that is currently solving the problems

so I see the code of problem E

and I would say that it is very familiar to a lot of codes that get AC here at the time that it published

now a lot might say why would i care about div4

a lot of people waits div4 for positive delta

and I know coders that was getting around +100 rating

but because of that they got negative delta because they didn't come up with problem E

I will add some photos

my point is

cheating is bad for you

but if you don't care

just don't ruin contest for other people
