Q1. The hiring manager asked me to code the right view of the tree.
Ans. 
Implement a function to return the right view of a binary tree.
• Use a level order traversal (BFS) to explore the tree.

• Keep track of the last node at each level to form the right view.

• Utilize a queue to facilitate the traversal of nodes level by level.

• Example: For the tree [1, 2, 3, null, 5, null, 4], the right view is [1, 3, 4].
