新手村 循环 级数求和

#include <cstring>#include <iostream>#include <cmath>#include <stdio.h>#include <stdlib.h>#include <string>#include <iomanip>using namespace std;int main() {    int k;    cin >> k;    double sum = 0;    int cnt = 0;    while(sum <= k) {        cnt++;        sum += 1.0 / cnt;    }     cout << cnt << endl;}

这题目只要对着写就好了。
