C :

#include<stdio.h>
int main()
{
    int i;
    int n;
    scanf("%d",&n);
    for(i=1000;i<=n;i++)
    {
        if(i%2==1)
        {
            if(i/1000==i/10%10&&i/100%10==i%10)
            printf("%d\n",i);
        }
    }
    return 0;
}

C++ :

#include <bits/stdc++.h>;
using namespace std;
int main(){
	int n,i;
	int q,b,s,g;
	cin>>n;
	for(i=1000;i<=n;i++){
		q=i/1000;
		b=i/100%10;
		s=i/10%10;
		g=i%10;
		if(q==s&&b==g&&i%2==1){
			cout<<i<<endl;
		}
	}
}

Java :

import java.util.Scanner;
public class Main
{
    public static void main(String[] args){
       Scanner sc = new Scanner(System.in);     
       int n = sc.nextInt();
       for(int i=1000;i<=n;i++) {
            int a =i/1000;
            int b =i/100%10;
            int c =i/10%10;
            int d =i%10;
            int x =1000*c+100*d+10*a+b;
            if(x==i && i%2==1) {
            	System.out.println(i);
            }
         } 
            
   }
}

Python :

n = int(input())
for i in range(1000, n + 1):
    q = i // 1000 % 10
    b = i // 100 % 10
    s = i // 10 % 10
    g = i // 1 % 10
    if q == s and b == g and i % 2 == 1:
        print(i)
