    long long cout = 0;
    scanf("%d", &k);
    for (double i = 1; sum < k; i++)
    {
        sum += 1.0/i;
        cout++;

#include<bits/stdc++.h>
using namespace std;
int main()
{
    int k,i=1;
    double s=0.0;
    cin>>k;
    while (k>=s){
        s+=1.0/i;
        i++;
    }
    cout<<i-1;
}

@benxin200563 求关

@benxin200563 建议你用while循环，这会比for循环好一点

@benxin200563 还有，用ld来输出就好了。

@chenxitao 有一个插入代码，然后选c类型的代码就好了
