Hi codeforces. Recently I have just noticed that many newbies copy others people code of problems rated higher than 2500-3000. I have some examples, and I don't it's by rules to copy others codes.
Lakibaja : first code Acanikolic73 : second code Andrijanikolic73 : third code
These three codes are exactly same(LazarNikolic submitted it in like 2 mins(he usually can't solve more than 2 problems on div4)
That submission was copied from tenkei : him code
I just think it's not ok to do that(I think like 3-4 days ban will be good thing for this people)
