Grokking the Coding Interview Patterns in C#

Solution: Palindrome Number

Understand how to identify palindrome numbers using a mathematical approach that reverses only half of the digits. This lesson teaches you to handle special cases, avoid integer overflow, and achieve efficient time and space complexity for coding interviews.

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 ...
