Step 1: Understand what an AVL tree is. It is a type of binary search tree that keeps itself balanced.
Step 2: Learn about the balance factor. The balance factor is the difference in height between the left and right subtrees of a node.
Step 3: Know the rule for balance. In an AVL tree, the balance factor must be -1, 0, or 1. This means the heights of the left and right subtrees can differ by at most one.
Step 4: Recognize the importance of balance. Keeping the tree balanced ensures that operations like searching, inserting, and deleting can be done quickly.
Step 5: Conclude that the primary purpose of using AVL trees is to maintain balance for efficient operations.
