My issue

Why my code is failing?

My code

#include <stdio.h>
#include<stdlib.h>
int main() {
    // your code goes here
    int t;
    scanf("%d", &t);
    while (t--)
    {
        int x, y;
        scanf("%d %d", &x, &y);
        if (y > x)
        {
            int temp = y;
            y = x;
            x = temp;
        }
        if(x >= 2*y)
        {
            printf("0\n");
        }
        else
        {
            if(x % 2 != 0)printf("%d\n", 2*y-x);        
            else
            {
                if(abs(2*y-x) < abs(x/2-y))printf("%d\n", abs(2*y-x));
                else printf("%d\n", abs(x/2-y));
            }
        }
    }

}
