Bottom View of a Binary Tree

Priya only reaches for Bottom View of a Binary Tree (alt) when folder on disk has to stay correct in a file explorer.

Keep Bottom View of a Binary Tree (alt) small. Priya should finish folder on disk in a few lines, not a 40-line dump.

Skip Bottom View of a Binary Tree (alt) and unbalanced BST becoming a list shows up in a file explorer.

Priya ships Bottom View of a Binary Tree (alt) in a file explorer. That is the use case worth saying.

Bottom View of a Binary Tree (alt) trap — unbalanced BST becoming a list. Priya loses marks for that every viva.

Bottom View of a Binary Tree (alt) is not a lonely heading. Priya ties it to folder on disk.

One breath for Bottom View of a Binary Tree (alt), then folder on disk, then unbalanced BST becoming a list. Sit down.

Exam tip

Say Bottom View of a Binary Tree (alt) in one breath, then left < root < right, then unbalanced BST becoming a list.

Example

class Node:
    def __init__(self, val, left=None, right=None):
        self.val, self.left, self.right = val, left, right

def inorder(n):
    if not n:
        return []
    return inorder(n.left) + [n.val] + inorder(n.right)

root = Node(2, Node(1), Node(3))
print(inorder(root))

Bottom View of a Binary Tree (alt) — inorder walks left → node → right (sorted order for a BST).
