C :

#include<stdio.h>
#include<math.h>
int main()
{
	int i,a,b,c,m,n,d,s=0,e;
	scanf("%d%d",&m,&n);
	for(i=m;i<=n;i++)
	{
		a=i;
		c=-1;
		while(a>0)
		{
			c++;
			a=a/10;
		}
		a=i;
		d=0;
		for(b=c;b>=0;b--)
		{
			e=a%10;
			a=a/10;
			d+=e*pow(10,b);
		}
		if(d==i){
			printf("%d\n",i);
			s++;
		}
	}
	 printf("%d",s);
	 return 0;
 } 

C++ :

#include <iostream>
using namespace std;

int main(){
	int m,n,c=0,i;
	cin>>m>>n;
	for(i=m;i<=n;i++){
		if(i/100==i%10){
			cout<<i<<endl;
			c++;
		}
	}
	cout<<c;
}

Java :

import java.util.Scanner;

public class Main{
	public static void main(String[] agrs){
	
	Scanner sc = new Scanner(System.in);

	int m = sc.nextInt();
	int n = sc.nextInt();
	int num = 0;
	for(int i = m;i <= n;i++){
		if(i / 100 == i % 10){
				System.out.println(i);
				num++;
		}
	
	}
	System.out.println(num);
	}
}

Python :

s = input().split()
m = int(s[0])
n = int(s[1])
c = 0
for i in range(m, n + 1):
    b = i // 100 % 10
    s = i // 10 % 10
    g = i // 1 % 10
    if b == g:
        print(i)
        c += 1
print(c)
