Populating Next Right Pointers in Each Node

Understand how to connect each node in a perfect binary tree to its immediate right neighbor by setting next pointers. This lesson guides you through implementing an efficient tree breadth-first search solution, helping you master key tree traversal and pointer manipulation techniques using C++.

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.
