Reverse Integer — C# Coding Problem
Difficulty: easy | Category: math
Problem Description
Given a signed 32-bit integer `x`, return `x` with its digits reversed. If reversing `x` causes the value to go outside the signed 32-bit integer range `[-2^31, 2^31 - 1]`, then return `0`. Assume the environment does not allow you to store 64-bit integers (signed or unsigned).
Examples
Example 1
Input: x = 123
Output: 321
Example 2
Input: x = -123
Output: -321
Example 3
Input: x = 120
Output: 21
