Grokking the Coding Interview Patterns in C#

Populating Next Right Pointers in Each Node

Explore how to connect all nodes at the same level in a perfect binary tree by setting their next pointers to the immediate right node. Understand the problem constraints and implement an efficient solution using breadth-first search, preparing you to solve similar tree traversal challenges in coding interviews.

We'll cover the following...

Statement

Given a perfect binary treeA binary tree in which all the levels are completely filled with nodes, and all leaf nodes (nodes with no children) are at the same level., where each node contains an additional pointer called next. This pointer is initially set to NULL for all nodes. Your task is to connect all nodes of the same hierarchical level by setting the next pointer to its immediate right node.

The next pointer of the rightmost node at each level is set to NULL.
