The vertical order traversal of a binary tree is a list of top-to-bottom orderings for each column index starting from the leftmost column and ending on the rightmost column. There may be multiple nodes in the same row and same column.
Given a Binary Tree, find the vertical traversal of it starting from the leftmost level to the rightmost level. If there are multiple nodes passing through a vertical line, then they should be printed as they appear in level order traversal of the tree. Examples: Input: 1.
Aug 17, 2024 · The following examples illustrate the vertical order traversal. Input: 1. / \ 2 3. / \ / \ 4 5 6 7. / \ 8 9. Output: 4. 2. 1 5 6. 3 8. 7. 9. Brute Force Approach : O (n^2) We traverse the tree and find the Horizontal Distances (HD) of the leftmost and rightmost nodes.
Oct 9, 2024 · Given a Binary Tree, the task is to find its vertical traversal starting from the leftmost level to the rightmost level. If multiple nodes pass through a vertical line, they should be printed as they appear in the level order traversal of the tree.
In a vertical order traversal, we are required to group and print out the values of the nodes that are in the same vertical level—imagine drawing vertical lines through the nodes. The nodes that intersect with the same line are in the same vertical level and should be grouped together.
An efficient method for visiting nodes in a binary tree according to their vertical distances from the root is to traverse the tree vertically using a map. This traversal enables grouping nodes according to their respective vertical lines in the tree by assigning each node a vertical distance and using a map data structure.
In this topic, we will see the vertical traversal of a binary tree. For the vertical traversal, we will calculate the horizontal distance. We will assign the horizontal distance to every node, and the horizontal distance could be from any side of the tree.
