Solution: Largest Number After Digit Swaps by Parity
Explore how to solve the problem of creating the largest possible integer by swapping digits that share the same parity. This lesson teaches you to use max-heaps to separate odd and even digits for efficient retrieval and replacement, ensuring you understand time and space tradeoffs while applying this strategy in coding interviews.

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.
