Palindromes with stacks

Use stacks to tell, for every given sequence of numbers, if the sequence
is a palindrome or not. That is, you must tell if the sequence reads the
same from left to right than from right to left (without reversing the
digits of each number).

Input

Input consists of several sequences of numbers, one per line.

Output

For every line, print “It is a palindrome.” or “It is NOT palindrome.”
as required.

Observation

To solve this exercise, the only containers that you should use are
stacks of integer numbers.
