Practice Questions

Q1
In which scenario would a Red-Black tree be preferred over an AVL tree?
  1. When frequent insertions and deletions are expected.
  2. When memory usage is a critical factor.
  3. When the dataset is static and does not change.
  4. When the tree needs to be perfectly balanced.

Questions & Step-by-Step Solutions

In which scenario would a Red-Black tree be preferred over an AVL tree?
  • Step 1: Understand what a Red-Black tree is. It is a type of self-balancing binary search tree that ensures the tree remains approximately balanced.
  • Step 2: Understand what an AVL tree is. It is another type of self-balancing binary search tree, but it is more rigidly balanced than a Red-Black tree.
  • Step 3: Know that both trees are used to maintain sorted data and allow for efficient search, insertion, and deletion operations.
  • Step 4: Recognize that Red-Black trees allow for faster insertions and deletions because they are less strict about balancing compared to AVL trees.
  • Step 5: Conclude that if your application requires frequent insertions and deletions, a Red-Black tree would be preferred over an AVL tree.
