Questions & Step-by-Step Solutions

Which of the following is a characteristic of AVL trees?
  • Step 1: Understand what an AVL tree is. It is a type of binary search tree that keeps its height balanced.
  • Step 2: Know that 'height' refers to the number of levels in the tree from the root to the furthest leaf.
  • Step 3: Learn that AVL trees automatically adjust themselves when nodes are added or removed to keep the height balanced.
  • Step 4: Recognize that the height of an AVL tree with 'n' nodes is approximately log(n), which means it grows slowly as more nodes are added.
  • Step 5: Understand that this height balance allows AVL trees to perform operations like searching, inserting, and deleting efficiently.
