Solution: Sort Array By Parity II
Explore how to efficiently sort an array by parity using a modified cyclic sort approach combined with two pointers. Understand how to position even numbers at even indexes and odd numbers at odd indexes in-place with minimal operations. This lesson helps you grasp the technique and implement a solution with linear time complexity and constant space usage.

Statement
You are given an integer array, nums, where exactly half of the elements are even, and the other half are odd.
Rearrange nums such that:
All even numbers are placed at even indexes
