Solution: Binary Tree Right Side View

Explore how to implement a depth-first search to obtain the right side view of a binary tree. Learn to track node levels, prioritize right children in traversal, and collect visible nodes in a list. This lesson helps you understand a practical DFS application, analyze time and space complexities, and code an efficient solution in Go.

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
