Problem: Binary Tree Right Side View

Explore how to implement a function that returns the right side view of a binary tree. Learn to use breadth-first search to traverse each tree level, capturing the rightmost visible node from top to bottom. Understand the time and space complexities involved in this solution.

We'll cover the following...

Statement

Given the root of a binary tree, imagine you are standing on the right side of the tree. Return the values of the nodes that are visible from this perspective, ordered from top to bottom.

In other words, for each level of the tree, return the value of the rightmost node that is visible when the tree is viewed from the right side.

Constraints:

  • The number of nodes in the tree is in the range [0,100][0, 100].

  • −100≤-100 \leq Node.data ≤100\leq 100 ...
