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 \(\frac{|a-b|}{\max(1,|b|)} \le 10^6\).
