*```cpp 代码：#include <bits/stdc++.h> using namespace std; int main() { long long int n; cin >> n; while (n != 1) { if (n % 2 == 0){ cout << n << "/2=" << n / 2 << endl; n = n / 2;} else {cout << n << "3+1=" << n 3 + 1 << endl; n = n 3 ;}} else cout << "End" << endl; return 0; }

@makeway 《n = n * 3》

没加一。

H_n = \sum_{i = 1}^{n} \frac{1}{i}
