c++,这个怎么错了？（TLE）

#include <iostream>
using namespace std;

int main() 
{
    int i,n,k,m=1;
    cin>>k;
    for(i=2;m<k;i++)
    {
        m+=1/i;
    }
    cout<<i;
    return 0;
}

#include<bits/stdc++.h>
using namespace std;
long long k,i;
double s=0.0;
int main() {
    cin >> k;
    for (i=1; s<=k; i++) 
        s=s+1.0/i;
        cout << i-1;
    return 0;
}

@杜雨峰 用double

by jijidawang @ 2020-03-07 11:08:39

@杜雨峰 你改成1.0/i，要不然整形都是0

@杜雨峰 整形您敢做？
