int main()
{
    double n;
    cin>>n;
    for(double i=1;true;i++)
    {
        q=q+1/i;
        if(q>=n)
        {
            cout<<i;
            return 0;

求关注QWQ

#include<bits/stdc++.h>
using namespace std;
int main()
int k;
int sum = 0;
{
    cin >> k;
    for(double i = 0 ; i <= k; ++sum , i += 1.0 / sum);
    cout<< sum;
    return 0;
}
