The length of the segment


Given four real numbers representing cartesian coordinates: \( \left ( x_{1}, y_{1} \right ), \left ( x_{2}, y_{2} \right ) \). Write a function distance(x1, y1, x2, y2) to compute the distance between the points \( \left ( x_{1}, y_{1} \right ) \) and \( \left ( x_{2}, y_{2} \right ) \). Read four real numbers and print the resulting distance calculated by the function.

The formula for distance between two points can be found at Wolfram.
