	 long int number, reverse=0, rem, original;
	 clrscr();

	 scanf("%ld", &number);
	
	 original = number;
	 
	 // Finding Reverse
	 while(number!=0)
	 {
	  rem = number % 10;
	  reverse = reverse*10 + rem;
	  number = number/10;
	 }
	 
	 // Checking for Palindrome
	 if(original == reverse)
	 {
	  printf("%ld is PALINDROME.", original);
	 }
	 else
	 {
	  printf("%ld is NOT PALINDROME.", original);
	 }
