Problem: Vertical Order Traversal of a Binary Tree

Medium
30 min
Understand how to implement vertical order traversal on a binary tree by applying breadth-first search techniques. Learn to return node values column by column, top to bottom, and resolve conflicts when nodes share the same row and column. This lesson helps you grasp an essential tree traversal pattern useful for coding interviews.

Statement

Find the vertical order traversal of a binary tree when the root of the binary tree is given. In other words, return the values of the nodes from top to bottom in each column, column by column from left to right. If there is more than one node in the same column and row, return the values from left to right.

Constraints:

  • The number of nodes in the tree is in the range [1, 500].
  • 00 \leq Node.data 1000\leq 1000
