Solution: Populating Next Right Pointers in Each Node
Explore how to connect each node's next pointer to its right neighbor in a perfect binary tree using breadth-first search. Understand both naive and optimized approaches, their complexities, and apply tree traversal techniques to solve this coding interview problem efficiently.
Statement
Given a 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
