Vertical Order Traversal of a Binary Tree

Explore how to solve vertical order traversal of a binary tree by returning node values column-wise from top to bottom and left to right. Learn to implement this using breadth-first search, improving your ability to handle tree traversal problems efficiently.

We'll cover the following...

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].
