“高教社杯”第三届福建省大学生程序设计竞赛

为高教杯复习而做，水题

直接贴AC代码：

#include<stdio.h>

int f(double x) {

    int i;

    for(i = 0; i <= 10000; i++)

        if(x >= i && x < i+1)

            break;

    return i;

}

int main() {

    int T;

    scanf("%d", &T);

    while(T--) {

        int n, l, r;

        int sum = 0;

        scanf("%d %d %d", &n, &l, &r);

        for(int i = l; i <= r; i++) {

            double num = n / i;

            sum += f(num);

        }

        printf("%d\n", sum);

    }

    return 0;

}
