Solution: Populating Next Right Pointers in Each Node
Explore how to connect the next pointers of nodes at each level in a perfect binary tree. Understand both naive and optimized breadth-first search methods to establish these links with clear algorithmic approaches, improving your grasp of tree traversal patterns for coding interviews.
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
