How does the insertion operation in a Red-Black Tree differ from that in an AVL Tree?
  1. Red-Black Trees require fewer rotations
  2. AVL Trees allow duplicate values
  3. Red-Black Trees are always balanced
  4. AVL Trees are faster for insertion

Questions & Step-by-Step Solutions

How does the insertion operation in a Red-Black Tree differ from that in 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 when you insert a new node, both trees need to maintain their balance properties.
  • Step 3: In an AVL Tree, after inserting a node, you may need to perform rotations to maintain the balance factor (the difference in heights of left and right subtrees) of each node.
  • Step 4: In a Red-Black Tree, after inserting a node, you also need to fix any violations of the Red-Black properties, but this usually requires fewer rotations than in an AVL Tree.
  • Step 5: Conclude that the main difference is that Red-Black Trees often need fewer rotations during insertion compared to AVL Trees.
  • Red-Black Tree vs. AVL Tree Insertion – The insertion operation in Red-Black Trees involves fewer rotations and rebalancing steps compared to AVL Trees, which maintain a stricter balance.
