Problem: Populating Next Right Pointers in Each Node

Medium
30 min
Explore how to connect nodes horizontally at each level in a perfect binary tree by setting the next pointer to the adjacent right node. This lesson helps you understand the breadth-first search approach for this problem, practice implementing your solution, and handle constraints effectively.

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 [0,500][0, 500].
  • 1000-1000 \leq Node.data 1000\leq 1000
