Problem: Binary Tree Right Side View

Explore how to identify the rightmost visible nodes of a binary tree from top to bottom by applying a breadth-first search traversal. Learn to implement a queue-based level order traversal to capture these nodes efficiently and analyze the solution's time and space complexity.

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 ...
