Solution: Largest Number After Digit Swaps by Parity
Explore how to rearrange digits of a number to form its largest value by swapping digits with the same parity. This lesson teaches you to use max-heaps for odd and even digits, enabling efficient swapping and maximizing the number while maintaining parity constraints. Understand time and space complexity to grasp the algorithm's efficiency.

Statement
You are given a positive integer num. You can swap any two digits of num as long as they share the same parity (both are odd or both are even).
Your task is to return the largest possible value of num after performing any number of such swaps.
Constraints:
num
Solution
The algorithm rearranges the digits of a given integer ...
