import java.util.Scanner;
class Main {
int n, num, rev = 0, r;
Scanner sc = new Scanner(System.in);
void input() {
System.out.print("Enter a number:");
n = sc.nextInt();
num = n;
}
void check() {
while (n > 0) {
r = n % 10;
rev = rev * 10 + r;
n = n / 10;
}
if (num == rev) {
System.out.println("Number is palindrome:" + num);
} else {
System.out.println("Number is not palindrome:" + num);
}
}
public static void main(String args[]) {
Main rr = new Main();
rr.input();
rr.check();
}
}
