Q1
In which scenario would an AVL tree be preferred over a Red-Black tree?
  1. When insertions and deletions are more frequent than searches.
  2. When search operations are more frequent than insertions and deletions.
  3. When memory usage is a concern.
  4. When the dataset is small.

Questions & Step-by-Step Solutions

In which scenario would an AVL tree be preferred over a Red-Black tree?
  • Step 1: Understand what AVL trees and Red-Black trees are. Both are types of self-balancing binary search trees.
  • Step 2: Know that AVL trees are more strictly balanced than Red-Black trees, which means they keep their height smaller.
  • Step 3: Recognize that a smaller height in a tree leads to faster search operations because there are fewer nodes to check.
  • Step 4: Identify the scenario where search operations are more frequent than insertions and deletions. This means you need to find values in the tree often.
  • Step 5: Conclude that in this scenario, an AVL tree is preferred because it provides faster search times due to its stricter balancing.
