Problem 172. Test if a Number is a Palindrome without using any String Operations
Description
Given an integer X, determine if it is a palindrome number. That is, X is equal to the X with the digits reversed (with no leading 0s). The twist is that your code cannot use any function or variable name that has either "str", "eval", "flip" or "printf" in it.
Example
X = 123454321; Y = true;
X = 1234; Y = false;

Nice expression for the usage test. Maybe one can add function "dec2base", cause the return type is a String.

The problem description should mention that dec2base isn't allowed either.
