求助，不清楚，这题哪里错了，自己运行的时候好像答案跟他是一样的。

#include <stdio.h>

struct book {
    char title[31];
    float price;
};

int main() {
    int n;
    scanf("%d", &n);
    if(n <= 0 || n >= 10) {
        return 0;
    }
    struct book books[n];
    for (int i = 0; i < n; i++) {
        getchar();  // 读取换行符
        fgets(books[i].title, sizeof(books[i].title), stdin);
        scanf("%f", &books[i].price);
    }
    if(n == 1) {
        printf("%.2f, %s", books[0].price, books[0].title);
        return 0;
    }

    for (int i = 0; i < n - 1; i++) {
        for (int j = 0; j < n - i - 1; j++) {
            if (books[j].price < books[j + 1].price) {
                struct book temp = books[j];
                books[j] = books[j + 1];
                books[j + 1] = temp;
            }
        }
    }

    printf("%.2f, %s", books[0].price, books[0].title);
    printf("%.2f, %s", books[n - 1].price, books[n - 1].title);

    return 0;
}

可是它就是提示最小 n，答案错误 ![image|690x194](/uploads/image/4b/9c/4b9c52be61ab1c6202622a744b6b74437b1b3c3a92bc2340f0a11966bc8eb9a5.avif)
