"""
you are given three integers represnting the positions of three people on a
number line. 'x' is the position of person 1, 'y' is the position of person
2, and 'z' is the position of persion 3 who does not move. both person 1 and
person 2 move toward person 3 at the same speed. determine which person will
reach person 3 first. return 1 if person 1 will arrive first, return 2 if
person 2 will arrive first, and 0 if both arrive at the same time.
