Efficient Integer Reversal with 32-bit Overflow Constraints
The task involves inverting the digits of a standard 32-bit signed integer. For example, an input of 123 produces 321, while -789 yields -987. A critical requirement dictates that the function must return 0 if the reversed value exceeds the representabel range of a 32-bit signed integer (-2,147,483,648 to 2,147,483,647).
String-Based Inversion
