Vertical Order Traversal of a Binary Tree

Explore how to implement vertical order traversal of a binary tree by returning node values from top to bottom in each column and left to right within the same row. This lesson helps you understand the problem constraints, conceptualize the traversal order, and apply breadth-first search techniques to solve the problem efficiently.

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 ...
