3516. Find Closest Person

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 1 if Person 1 arrives first.
• Return 2 if Person 2 arrives first.
• Return 0 if both arrive at the same time.

Return the result accordingly.

class Solution {
public:
    int findClosest(int x, int y, int z) {
        int xz = abs(x-z), yz = abs(y-z);
        return xz < yz ? 1 : xz > yz ? 2 : 0; 
    }
};
