Q1
In which scenario would you prefer using an AVL tree over a Red-Black tree?
  1. When frequent insertions and deletions are required.
  2. When search operations are more frequent than insertions.
  3. When memory usage is a concern.
  4. When the tree needs to be unbalanced.

Questions & Step-by-Step Solutions

In which scenario would you prefer using an AVL tree over a Red-Black tree?
  • Step 1: Understand what an AVL tree is. It is a type of self-balancing binary search tree where the difference in heights between the left and right subtrees is at most 1.
  • Step 2: Understand what a Red-Black tree is. It is another type of self-balancing binary search tree that allows for a bit more flexibility in balancing, which can lead to faster insertions and deletions.
  • Step 3: Compare the performance of AVL trees and Red-Black trees. AVL trees are generally faster for search operations because they are more strictly balanced.
  • Step 4: Identify scenarios where search operations are more frequent than insertions or deletions. For example, if you have a database that mostly retrieves data and rarely updates it.
  • Step 5: Conclude that in scenarios with frequent search operations, you would prefer using an AVL tree over a Red-Black tree due to its faster lookup times.
