Given therootof a binary tree, calculate the vertical order traversal of the binary tree. For each node at position(row, col), its left and right children will be at positions(row + 1, col - 1)and(row + 1, col + 1)respectively. The root of the tree is at(0, 0). The vertical...

If we are given a binary tree and we need to perform a vertical order traversal, that means we will be processing the nodes of the binary tree from left to right. Suppose we have a tree such as the one given below. If we traverse the tree in vertical order and print the nodes then...
Given a binary tree, return the vertical order traversal of its nodes values. For each node at position (X, Y), its left and right children respectively will be at positions (X-1, Y-1) and (X+1, Y-1). Running a vertical line from X = -infinity to X = +infinity, whenever the...

Create a binary tree or take it as input from the user. Find the horizontal distance of each node from the root using recursion, and get the minimum and maximum value of the distance. Traverse through the tree and compare the distance of each node to check- ...

Given a binary tree, return the vertical order traversal of its nodes' values. (ie, from top to bottom, column by column). If two nodes are in the same row and column, the order should be from left to right. Examples 1: Input: [3,9,20,null,null,15,7] ...
