Not a Geometry Problem
Description
The only line of input contains three integers $x$, $y$, $z$ ($-1000 \le x, y, z \le 1000$).
Output one real number — the answer.
Your answer is considered correct if its absolute or relative error does not exceed $10^6$. Formally, let your answer be $a$, and the jury's answer be $b$. Your answer is accepted if and only if $\frac{|a-b|}{\max(1,|b|)} \le 10^6$.
