I apologize for my poor English.
What I mean is some of the test cases provided by alimbubt were invalid, like "278.42".
With my code it won't output 0, it shows 99254706249644.

Thanks for your help, I got AC!

Please help me. Don't know why get WA.
I've tested the above test cases.
Since the problem says each test case will be valid, I get the same output but invalid cases.
Does it matter?

My code: Thanks for your reading!
