Solution: Sort Array By Parity II
Explore how to rearrange an integer array where half the elements are even and half are odd so that even numbers occupy even indexes and odd numbers occupy odd indexes. Learn a modified cyclic sort technique combined with two pointers to swap misplacements in place, resulting in a solution with linear time and constant space complexity.
