2. using namespace std;
3. int main()
4. {
5.     int palindrome, reverse=0;
6.     cout<<"Enter number:  ";
7.     cin>>palindrome;
8.     int num=0,key=palindrome;
9. for(int i=1;palindrome!=0;i++){
10. 
    
11.     num=palindrome%10;
12.     palindrome=palindrome/10;
13.     reverse=num+(reverse*10);
14.               }
15. 
    
16.    if(reverse==key){
17.    cout<<key<<" is a Palindrome Number";
18.             }
19.             else{
20.    cout<<key<<"is NOT a Palindrome Number";
21.             }
