菜鸟求助！！！

#include <bits/stdc++.h>
int a[100005], b[100005];
using namespace std;
int main() {
    int n;
    double x, y;
    scanf("%d", &n);
    for (int i = 1; i <= n; i++)
        scanf("%d%d", &a[i], &b[i]);
    x = b[1] / a[1] * 1.0;
    for (int i = 2; i <= n; i++) {
        y = b[i] / a[i] * 1.0;
        if(y - x > 0.05)
            printf("better\n");
        else if(x - y > 0.05)
            printf("worse\n");
        else
            printf("same\n");
    }
    return 0;
}

为啥全输出same呢？
