/***************************************************************************************************** 
 *
 * 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 [-231, 231 - 1], then return 0.
 * 
 * Assume the environment does not allow you to store 64-bit integers (signed or unsigned).
 * 
 * Example 1:
 * Input: x = 123
 * Output: 321
 * Example 2:
 * Input: x = -123
 * Output: -321
 * Example 3:
 * Input: x = 120
 * Output: 21
 * Example 4:
 * Input: x = 0
 * Output: 0
 * 
 * Constraints:
 * 
 * 	-231 <= x <= 231 - 1
