They require more memory than binary search trees.
Questions & Step-by-Step Solutions
Which of the following statements is true about AVL trees?
Step 1: Understand what AVL trees are. They are a type of self-balancing binary search tree.
Step 2: Learn about the balancing property of AVL trees. They maintain a balance factor of -1, 0, or +1 for every node.
Step 3: Compare AVL trees with Red-Black trees. Red-Black trees are also self-balancing but allow for a bit more flexibility in balancing.
Step 4: Recognize that because AVL trees are more rigidly balanced, they can provide faster search times compared to Red-Black trees.
Step 5: Conclude that the statement about AVL trees being more rigidly balanced than Red-Black trees, which helps in maintaining faster search times, is true.
