You've got the AC? as may be the answer?

if all friends and Dan drank equally, then each are drank at 2.8 liters => each of them has bought more than drinking

sorry for bad english :)

I think it should be 100 0 0 0 0.
Because everyone drank 3,8l and 4 of them bought 3l and Dan doesn't have to pay them.

Why?
They brought 5+3+3+3+3 = 17, so everyone drank 17/6 = 2,8(3).

This wtf situation from precision.
Эта всё из-за точности.

For example:
Например:
4.99999999999999999999999999
But in real this is 5. When this are arounded in floor we get 4.
Но на самом деле это число 5. А при округлении вниз получаем 4.

So!
Итак!

This get WA9
floor(100.0*(a[i]-half)/mt);

But this get AC
floor(100.0*(a[i]-half)/mt+0.0001);

P.S.: get 10 times WA9 =)

+0.0001 gave me WA#11
but +0.00001 gives AC ;)

Friends!
Problem can be solved easy in int type only without any 0.0001 and so on.
Multiply all by common denumenators and have joy of AC.

min multiplied coefficient is 5 - to get the AC=)(on Java)
on c++ I used coefficient - 1000
