Solution: Populating Next Right Pointers in Each Node

Understand how to connect nodes at the same level in a perfect binary tree by populating their next right pointers. Explore both a naive BFS approach using a queue and an optimized solution leveraging tree structure for O(1) space. This lesson helps you master efficient level order traversal and node linking in binary trees.

We'll cover the following...

- Naive approach
- Optimized approach using Tree Breadth-first Search

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.

Constraints:

The number of nodes in the tree is in the range
