Solution: Sort Array By Parity II
Explore the solution to Sort Array By Parity II by applying a modified cyclic sort combined with two pointers. This lesson helps you understand how to efficiently rearrange integers so that even elements occupy even indexes and odd elements occupy odd indexes. You will learn the step-by-step approach, analyze time and space complexity, and gain practical insight into implementing this in-place sorting technique for coding interviews.

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
. All odd numbers are placed at odd indexes
.
You may return any valid arrangement that satisfies these conditions.
