洛谷 P1035 级数求和 已知：S_n= 1+1/2+1/3+…+1/nS n =1+1/2+1/3+…+1/n。显然对于任意一个整数KK，当nn足够大的时候，S_nS n 大于KK...

#include 
#include 

int main()
{
    int n, k;
    double s;
    scanf("%d", &k);
    s = 0.0;
    n = 1;
    while (1)       //死循环
    {
        s = s + 1.0/n;     //求s=1+1/2+...+1/n
        if(s > k)       
        {
            printf("%d\n", n);
            break;      //跳出死循环
        }
        n++;
    }
    return 0;
}
