Print Bottom view of binary tree

Printing the bottom view of a binary tree refers to printing the nodes that are visible when viewed from the bottom of the tree. In other words, it is the set of nodes that would appear if we were to look at the binary tree from below, with the root node at the top and the leaves at the bottom.

To print the bottom view of a binary tree, we need to determine the horizontal distance of each node from the root node. Nodes that are at the same horizontal distance from the root node will appear in the same vertical line when viewed from below. The bottom view of the tree will then be the set of nodes that appear in the last vertical line(s) from left to right.

In some cases, a binary tree may have multiple nodes at the same horizontal distance from the root node. In such cases, the bottom view would consist of the node that is the farthest from the root node in that horizontal distance.

Printing the bottom view of a binary tree can be useful in various applications, such as visualizing the tree structure and analyzing its properties.

Print Bottom view of binary tree

In this post mentioning two solution which is used to print bottom view of binary tree.

Using sorted list

We can use a linked list which is store only horizontal distance element. Here given code implementation process.

Time complexity of above solution is O(n^2)

Using collection
