Largest Number After Digit Swaps by Parity

Explore how to reorder a number's digits by swapping only those with the same parity to form the largest possible number. Understand the constraints and implement solutions using the heaps pattern for effective data processing.

We'll cover the following...

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:

  • ...
