C ++ implements gray code (gray code) and graycode

A question asked by others today emphasizes the use of the division and Control Law =. =

Baidu gave me a gray code and wrote it.

Let's take a look at Baidu's Gray Code, especially in detail. I will post a picture:

 

The Code is as follows (header_file.h is a header file written by myself, including a common vector iostream ):

#include"header_file.h"using namespace std;vector<string> gray_code(int n){    if(n==1)    {        vector<string> v;        v.push_back("0");        v.push_back("1");        return v;    }    else    {        vector<string> v;        vector<string> v1;        v1=gray_code(n-1);                for(int i=0;i<v1.size();i++)        {            v.push_back("0"+v1[i]);        }        for(int i=(v1.size()-1);i>-1;i--)        {            v.push_back("1"+v1[i]);        }                return v;    }}int main(int argc,char *argv[]){    int n;    cout<<"input n:";    cin>>n;        vector<string> v;    v=gray_code(n);    for(int i=0;i<v.size();i++)    {        cout<<v[i]<<endl;    }}

 

Finally, the process is important, and the code is just a reflection of your logic -. -
