Questions & Step-by-Step Solutions
Why are Red-Black trees preferred in certain applications over AVL trees?
Step 1: Understand that both Red-Black trees and AVL trees are types of self-balancing binary search trees.
Step 2: Know that Red-Black trees have a set of rules (properties) that help keep the tree balanced.
Step 3: Learn that when you insert or delete a node in a tree, it may become unbalanced.
Step 4: Realize that to fix this imbalance, the tree may need to perform rotations (rearranging nodes).
Step 5: Compare the number of rotations needed for Red-Black trees and AVL trees during insertions and deletions.
Step 6: Understand that Red-Black trees usually require fewer rotations than AVL trees.
Step 7: Conclude that because Red-Black trees are more efficient with fewer rotations, they are preferred in applications where there are many updates (insertions and deletions).
