输入输出都正确，但是就是过不去检查

#include<cstdio>
#include<cmath>
#include<iostream>
using namespace std;
int main(){
    int k;
    cin>> k;
    double number=0;
    int tempNumber=1;
    for(;number<k;){
        number=number+(double)1.0/tempNumber;
        tempNumber++;
    }
    cout<<tempNumber;
    return 0;
}
