#include<iostream>

#include<cstdio>

using namespace std;

int main() {

double s=0;

int n=1;

int k;

cin>>k;

while(s<=k)

{
s=s+1/n;

n++;

}

cout<<n;

return 0; }

```cpp #include <iostream> using namespace std; int main() { int k,n = 0 ; cin >> k ; double Sn = 0.; while(Sn <= k) { n++; Sn += (1. / n); } cout << n << endl; return 0; } ```

s是double类型，n是整形（int）的，1/n是int类型的，所以你的s数据是错误的，应该是s+=1.0/n.
