Vertical Order Traversal of a Binary Tree

Explore how to implement vertical order traversal of a binary tree in Go. Understand how to return node values from top to bottom within each column and process columns from left to right, handling nodes on the same row with left to right order. This lesson helps you grasp traversal logic and apply it efficiently in 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 ...
