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.

\n\n

Assume the environment does not allow you to store 64-bit integers (signed or unsigned).

Example 1:

\n\n
\nInput: x = 123\nOutput: 321\n
\n\n

Example 2:

\n\n
\nInput: x = -123\nOutput: -321\n
\n\n

Example 3:

\n\n
\nInput: x = 120\nOutput: 21\n
