DIY: Populating Next Right Pointers in Each Node

Explore how to connect each next pointer in a perfect binary tree so that it points to the next right node on the same level or null if none exists. Understand the traversal and linking strategy to implement this efficient, pointer-based solution.

We'll cover the following...

Problem statement

You are given a perfect binary tree where all the leaves are on the same level and every parent has two children. We have added an additional next pointer to our TreeNode implementation. ...
