C :

#include<stdio.h>
int main()
{
    int m,n,t;
    scanf("%d",&m);
    n=m/100;
    t=m%10;
    if(n==t)
        printf("Y");
    else
        printf("N");
    return 0;
}

C++ :

#include <bits/stdc++.h>
using namespace std;

int main(){
    int n,g,b;
    cin>>n;
    b = n / 100;
    g = n % 10;
    if(b == g){
    	cout<<"Y";
	}else{
		cout<<"N";
	}
}
 

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 b = n / 100;
		if(g == b){
			System.out.println("Y");
		}else{
			System.out.println("N");
		}
	}

}

Python :

n = int(input())
b = n // 100 % 10
s = n // 10 % 10
g = n // 1 % 10
if b == g:
    print('Y')
else:
    print('N')
