What is the primary reason for using AVL trees over regular binary search trees?
Step 1: Understand what a binary search tree (BST) is. A BST is a tree structure where each node has at most two children, and the left child is less than the parent, while the right child is greater.
Step 2: Recognize that in a regular BST, the tree can become unbalanced. This means that one side of the tree can be much deeper than the other, making search operations slower.
Step 3: Learn about AVL trees. An AVL tree is a type of self-balancing binary search tree. It automatically keeps itself balanced after every insertion or deletion.
Step 4: Understand the importance of balance. A balanced tree means that the height (or depth) of the tree is minimized, which helps in keeping search operations efficient.
Step 5: Compare performance. In a balanced AVL tree, search operations can be done faster because the tree is more evenly distributed, leading to fewer comparisons needed to find a value.
