Distance between two points

Using the definition

class Point:
    """attributes: x, y"""

write a function

dist(p, q)

that returns the Euclidean distance between two points $p$ and $q$ . For example, the distance between the point $(0, 0)$ and the point $(30, 40)$ is 50.

Input

The input consists of several pairs of points (two non-negative integer numbers each).

Output

For each two points, print their Euclidean distance.
