先改long long类型

by zxckhj114514 @ 2024-12-22 20:46:15

int n -> long long n

@gaohuashengtx n=1 的时候没判

1. int \to long long
2. if(n/2==1)break;要放在外面
   hack:
   input:
   1
   your:

   1*3+1=4
   4/2=2
   2/2=1
   End

   ans:
   End

final:

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

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