# Problem CLine Segment Distance

## Input

The first line of input contains an integer $n$ ($n \leq 10000$) giving the number of test cases. Then follow $n$ lines each containing 8 integers $x_1\ y_1\ x_2\ y_2\ x_3\ y_3\ x_4\ y_4$, indicating a line segment from $(x_1, y_1)$ to $(x_2, y_2)$, and a line segment from $(x_3, y_3)$ to $(x_4, y_4)$. Coordinates have absolute value at most 10000.

## Output

For each test case, output the distance between the two line segments with 2 decimals of precision.
