Reorganize String

Explore how to rearrange characters in a string to ensure that no two adjacent characters are identical. Learn to assess whether a valid reorganization is possible and understand constraints. Practice implementing your solution in a hands-on coding environment to master the pattern.

We'll cover the following...
