Diego, knowing that calculating $$$A+B$$$ is the easiest problem ever created, decided to give you a problem that is just a little bit harder.

You are given 3 positive integers, $$$A$$$, $$$B$$$ and $$$C$$$. Your task is to compute $$$\frac{A+B}{C}$$$.

Input

In the first line, an integer, $$$T$$$ $$$(1 \le T \le 10^4)$$$, representing the amount of test cases.

Then, $$$T$$$ lines, each containing the 3 space-separated integers $$$A$$$, $$$B$$$, and $$$C$$$ $$$(1 \le A, B, C \lt 10^{50})$$$.

Output

$$$T$$$ lines, each containing the requested value with exactly 50 digits after the decimal point.

If the value would has more than 50 decimals, the rest should be *truncated*.
