include<iostream>

include<cmath>

include<cstdio>

include<algorithm>

using namespace std; int main() { int k; cin>>k; double s=0.000000; for(double i=2;i<20000000000;i++) { s+=1/i; if(s>k) { cout<<i; break; } } return 0; }

@倪天灿希望更丰富的展现？使用Markdown

我怎么觉得#没加上呢

有#号的，倍洛谷吃了

@zclclWJN #号被Markdown当成标题了

k改成long long

include<iostream>

#include<cmath>
#include<cstdio>
#include<algorithm>
using namespace std; 
long long k;
double s = 0.000000;
int main() 
{ 
    cin >> k; 
    for(double i=2;i<20000000000;i++) 
    { 
        s += 1/i; 
        if(s > k) 
        { 
            cout << i; 
            break; 
        } 
    } 
    return 0;
}

int最大为2147483647
