Maximum Width of a Binary Tree at depth (or height) h can be 2hwhere h starts from 0. So the maximum number of nodes can be at the last level. And worst case occurs when Binary Tree is a perfect Binary Tree with numbers of nodes like 1, 3, 7, 15, …etc. In worst case, valu...

first, and then visit the root node last.Depth-First Search is a method for traversing trees and can be used in various scenarios such as searching solution spaces, path problems, and more. It is suitable for cases where it is necessary to delve deep into the leaf nodes of the tree.
