Write a method called distance that accepts four integer coordinates x1, y1, x2 and x2 as parameters and computes the distance between points (x1, y1) and (x2, y2) on the Cartesian plane. The equation for the distance is

For example, the call of distance(1, 0, 4, 4) would return 5.0 and the call of distance(10, 2, 3, 15) would return 14.7648230602334.
