Description

Consider a scenario where you are given two Binary Search Trees (BSTs) and need to merge them. Describe the approach and thought process you would take to effectively merge these trees while maintaining the BST properties.

**1. Problem analysis :**Understanding the technical implications and complexities involved in merging BSTs is crucial.**2. Algorithmic thinking :**You should be able to devise a step-by-step process to merge the two BSTs efficiently.**3. Data structure knowledge :**A thorough understanding of BSTs and their properties is necessary for this task.**4. Attention to detail :**Merging BSTs requires careful attention to ensure that the end result maintains the BST invariants.

**1. Analytical skills assessment :**The question aims to assess your ability to analyze a complex problem and identify a solution.**2. Technical knowledge evaluation :**Your understanding of BSTs and related data structures is evaluated through this question.**3. Problem-solving capability :**The interviewer wants to understand how you address and solve technical challenges.**4. Approach to algorithmic challenges :**This assesses how you approach algorithm design and efficiency in your problem-solving process.

**1. Break down the problem :**Discuss breaking down the problem into smaller, manageable parts like tree traversal, node comparison, and merging.**2. Mention different strategies :**Consider explaining various strategies, such as in-order traversal and then merging two sorted arrays followed by constructing a balanced BST.**3. Discuss trade-offs :**Talk about the trade-offs for different methods you might choose, like time complexity vs. space complexity.
