7 - Reverse Integer\. Medium 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
