Reverse Number Logic Fix #7

Fixed the incorrect logic used to reverse a number with a while loop.
Removed the invalid use of reversed() on an integer and corrected the reverse algorithm.
Extracted each digit using num % 10 and built the reversed number with rev = rev * 10 + digit.
Updated the number using integer division (num //= 10) until it became 0.
The corrected implementation now produces the expected reversed number for valid integer inputs.
