Solution: Largest Number After Digit Swaps by Parity
Explore how to maximize an integer by swapping digits that share the same parity using max-heaps. This lesson teaches you to separate digits into odd and even groups, reorder them with heaps, and reconstruct the largest possible number under given constraints.

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...
