#include<bits/stdc++.h>
using namespace std;
int main(){
    double k,n=1,sn;
    cin>>k;
    while(1){
        sn+=1/n;
        if(sn>k)
            break;
        n++;
    }
    cout<<n;
    return 0;

条件改一下

#include<bits/stdc++.h>
using namespace std;
int main()
{
    int n=0,k;
    cin>>k;
    double sum=0;
    while(sum<=k)
    {
        n++;
        sum+=(double)1/n;
    }
    cout<<n;
    return 0;
}

记得关注哦！
