DIY: Populating Next Right Pointers in Each Node

Understand how to connect next right pointers in each node of a perfect binary tree. This lesson guides you through implementing a function to traverse and link nodes, helping you master tree traversal techniques crucial 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.
