Given a binary tree, the left view of a binary tree is the set of all those nodes visible from the left side of the binary tree. In other words it is the set of first node of every level. Method-1 (Using Recursion) The left view contains all nodes that are first in every level....
In this article, we'll explore the fundamentals of binary trees, describe common traversal techniques, and cover a few sample interview questions. By building a strong foundation, you'll be well-prepared to face a wide range of coding challenges. Let's dive in! Nodes, Edges, and Tree ...
