You are given three integers x, y, and z, representing the positions of three people on a number line:
x is the position of Person 1.y is the position of Person 2.z is the position of Person 3, who does not move.Both Person 1 and Person 2 move toward Person 3 at the same speed.
Determine which person reaches Person 3 first:
Return the result accordingly.
Example 1:
Input: x = 2, y = 7, z = 4
Output: 1
Explanation:
Since Person 1 reaches Person 3 first, the output is 1.
Example 2:
Input: x = 2, y = 5, z = 6
Output: 2
Explanation:
Since Person 2 reaches Person 3 first, the output is 2.
Example 3:
Input: x = 1, y = 5, z = 3
Output: 0
Explanation:
Since both Person 1 and Person 2 reach Person 3 at the same time, the output is 0.
Constraints:
1 <= x, y, z <= 100
