模拟一下

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