Height of Binary Tree After Subtree Removal Queries

Understand how to compute the height of a binary tree after removing specified subtrees based on queries. Learn to handle independent subtree removal, apply depth-first search traversal, and manage tree state to solve interview-style problems efficiently in C++.

Statement

We are given the root of a binary tree with nn nodes and an array, queries, of size mm. Each query represents the root of a subtree that should be removed from the tree. The task here is to determine the height of the binary tree after each query, i.e., once a subtree is removed. We'll store the updated heights against each query in an array and return it.

Note: A tree’s height is the number of edges in the longest path from the root to any leaf node in the tree.

A few points to be considered:

  • All the values in the tree are unique.

  • It is guaranteed that queries[i] will not be equal to the value of the root.

  • The queries are independent, so the tree returns to its initial state after each query.

Constraints:

  • 22 \leq ...
