Verify and modify inorder subsequence

Q: Verify and modify inorder subsequence

This question evaluates algorithm design and data-structure manipulation in the Coding & Algorithms domain, focusing on binary tree inorder traversal, subsequence detection, and computing the minimum edit operations under strict time and space constraints.

Question

Given a binary tree and a sequence of numbers, design an algorithm to check in O(n) time and O(

extra space whether the sequence is a subsequence of the tree’s inorder traversal. How would you modify the tree so that its inorder traversal contains the given sequence as a subsequence? What is the minimum number of operations (changing an existing node’s value or inserting a new node counts as
required to achieve this modification?
