Problem: Vertical Order Traversal of a Binary Tree

Explore how to implement vertical order traversal of a binary tree in C# by applying breadth-first search and sorting techniques. Understand how to assign coordinates to nodes, group them by column, and ensure correct ordering of nodes within columns. This lesson helps you grasp detailed tree traversal methods useful for structured data processing and problem-solving.

We'll cover the following...

Statement

Given the root of a binary tree, compute the vertical order traversal of the tree.

Each node is assigned a position (row,col)(row, col). The root is located at position (0,0)(0, 0). For any node at position (row,col)(row, col), its left child is at position (row+1,colāˆ’1)(row + 1, col - 1) ...
