I passed the test case above, but still WA, any suggestions? I tried adding various values of EPS to the answer, but it didn't help... Is there some special extra super duper test case?

[Jan]

For n=1 the result is 0.000.

[Leonid]

Yeah, that is what I print, but still WA
Could you please check this input?

Same output except the blank lines. Don't remember why I omitted the blank lines...

[Leonid]

I tried to skip blank lines, but still WA :?

[rio]

Getting WA too.
Maybe the judge IO might be broken. I had same problem with 10750,10752.
Could someone who got AC with the old server see if it still could get AC ?

I got ac on P10751 when I print 4 digits after the decimal point.
I met precision problem several times in the new version.
I did the same for P10750,but wa...
btw,my 10750 code got ac in the old system.

Still WA, no matter how many digits I print.

[pineapple]

do you get the correct formula?
if your code passed jan's data,you should get AC.
the formula is quite simple and trivial.
if you need,I can send you my ac code by pm or email.

I passed Jan's input but WA. Could you PM your AC code?

[pineapple]

Leonid,have you got my code?
btw,my two version for P10751,n^2 and nlogn both got wa.
I think there must be something wrong in the special judge for this problem and P216

[rio]

Thanks pineapple
I've got AC with printing 4 digits after decimal point.
