Palindromes with stacks P65072
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.
Public test cases
Input
1 2 3 4 4 3 2 1 11 22 33 11 22 33 27 21 27 21 27 21 27

It is a palindrome. It is NOT a palindrome. It is a palindrome. It is a palindrome.
