DIY: Populating Next Right Pointers in Each Node

Explore how to populate the next right pointers in each node of a perfect binary tree to point to its adjacent right node or null if none exists. This lesson guides you through implementing a traversal function to connect these pointers, helping you understand tree traversal and pointer manipulation for coding interviews.

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. ...
