Hi everyone,
Although I ranked 4th in the round, I found out that the jury's output has too few decimal places that it would REJECT contestants' output even if it has less than 10^-6 absolute error.
Please see this submission: 15819369
Test 13:
Expected: 0.60590128755364806866952789699571
Jury: 0.605901
Mine: 0.6059020876
Edit: they have fixed the solution
error between expected and your output is 8*10^-7 which is less than 10^-6 but
relative error is difference/value = (8*10^-7/0.6) which is 1.33*10^-6 which is more than 10^-6
LHS = (0.6059020876 — 0.60590128755364806866952789699571) / max(1, 0.60590128755364806866952789699571)
= 0.00000080004635193133047210300429 / 1
that's less than RHS 10^-6
Yes the relative error exceeds the limit but the absolute error does not. I am talking about the absolute error.
my bad,sorry
Согласен, 6-ти знаков в ответе недостаточно хранить. Участник не обязан согласно условию задачи предоставлять ответ ровно с 6-ю знаками после точки, так что, отличный пример! Жюри следует взять на заметку такой факт.
