Solution: Palindrome Number

Understand how to check if a number is a palindrome by reversing only half of it mathematically. Learn to handle special cases and avoid integer overflow while ensuring efficient time and space complexity.

We'll cover the following...

Statement

Given an integer, x, return TRUE if it is a palindrome; otherwise, FALSE.

A palindrome integer is one whose digits read the same from left to right and right to left.

Constraints:

  • −2−31≤-2^{-31} \leq x ≤231 ...
