100分但后两个点TLE

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