Solution: Largest Number After Digit Swaps by Parity
Understand how to use max-heaps to rearrange digits in a number by swapping only even with even and odd with odd digits. This lesson helps you implement a solution that efficiently constructs the largest possible number while respecting parity constraints. You will learn to analyze digit parity, use heaps for optimization, and evaluate the algorithm's time and space complexity in coding interview scenarios.

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...
