As stated in the statement, after spraying or aromatizing of fruit it may become to have fractional value.
25th test is the first case where you need to aromatize one flower and dearomatize another in such way that both of them have fractional value, but their sum is integer.

can someone give me some tips or tests?

My AC program works very slowly on the following test:
12
256 256 256 256 256 256 256 256 256 256 256 1

Can you add it to the testset?

"When a faryuk is sprayed upon with the deodorant, its aroma strength decreases by 25 percent. When a faryuk is scented, its aroma strength increases by 10 percent. (In both cases, the aroma strength can become fractional)."

The question is about what is the base for calculations of 10% and 25% if we spray one faryuk several times: is it 10% and 25% of _initial_ aroma strength of a faryuk, or 10%/25% of aroma strength which we got after first aromatization?

If we return 0 things
must we write return 0 or return ?
Also is not clear must we count returnings with 0 things?
Not clear 3: Can we take bottle with each returning?
