C++ :

#include<bits/stdc++.h>
using namespace std;
int main(){
	int n,g,s,b,q;
	cin>>n;
	g=n%10;
	s=n/10%10;
	b=n/100%10;
	q=n/1000%10;
	if(g==q)cout<<"yes"<<endl;
	else cout<<"no"<<endl;
	return 0;
}

Java :

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner sc = new Scanner(System.in);
		int n = sc.nextInt();
		int g = n % 10;
		int s = n / 10 % 10;
		int b = n / 100 % 10;
		int q = n / 1000;
		if(g == q && s == b){
			System.out.println("yes");
		}else{
			System.out.println("no");
		}
		sc.close();
	}

}

Python :

n= int( input() ) 
q=n//1000
b=n//100%10
s=n//10%10
g=n%10
if q==g and b==s:
    print('yes')
else:
    print('no')
