Solution: Binary Tree Right Side View

Explore how to return the right-side view of a binary tree by implementing depth-first search. You will learn to traverse the tree prioritizing right children and capture the first nodes visible at each depth. Understand the algorithm's logic and complexity for effective tree traversal.

We'll cover the following...

Statement

You are given a root of a binary tree that has n number of nodes. You have to return the right-side view in the form of a list.

A right-side view of a binary tree is the data of the nodes that are visible when the tree is viewed from the right side.

Constraints:

  • 0≤0 \leq n ≤100\leq 100
