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 ...

// Given a 32-bit signed integer, reverse digits of an integer. // Assume we are dealing with an environment which could only store integers within the 32-bit signed integer range: [−231, 231 − 1].
