Problem «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.

In all the problems input the data using input() and print the result using print().
