Questions & Step-by-Step Solutions

What is the primary reason for using a Red-Black tree over an AVL tree?
  • Step 1: Understand that both Red-Black trees and AVL trees are types of self-balancing binary search trees.
  • Step 2: Know that both trees keep their height balanced to ensure efficient operations.
  • Step 3: Learn that Red-Black trees use a color property (red or black) to maintain balance.
  • Step 4: Recognize that AVL trees maintain balance by ensuring the heights of subtrees differ by at most one.
  • Step 5: Realize that when inserting or deleting nodes, Red-Black trees often require fewer rotations to fix any imbalance.
  • Step 6: Conclude that because of fewer rotations, Red-Black trees can perform insertions and deletions faster than AVL trees.
