Q1
In which scenario would you prefer an AVL tree over a Red-Black tree?
When frequent insertions and deletions are expected
When search operations are more frequent than updates
When memory usage is a critical factor
When the tree needs to be perfectly balanced
AVL trees provide faster search times due to their stricter balancing, making them preferable when search operations are more frequent.

Q: In which scenario would you prefer an AVL tree over a Red-Black tree?
Solution: AVL trees provide faster search times due to their stricter balancing, making them preferable when search operations are more frequent.
Steps: 6
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 imbalance than AVL trees.
Step 3: Know that AVL trees are more strictly balanced than Red-Black trees, which means they keep their height smaller.
Step 4: Realize that a smaller height in a tree generally leads to faster search times because there are fewer nodes to check.
Step 5: Consider the scenario where you need to perform many search operations quickly. In this case, the faster search times of AVL trees make them a better choice.
Step 6: Conclude that if your application requires frequent searches and you want the best performance for those searches, you would prefer an AVL tree over a Red-Black tree.
