Problem: Vertical Order Traversal of a Binary Tree

Explore the process of computing vertical order traversal of a binary tree. Learn to perform BFS traversal while tracking node positions and sorting nodes column-wise by row and value to achieve the desired output. Understand implementation and complexity analysis to apply this technique effectively.

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) ...
