Final answer:
A ranked balance tree is a type of binary search tree where each node has an associated rank. There are different types of balanced trees, such as AVL trees, red-black trees, and B-trees.
Step-by-step explanation:
A ranked balance tree is a type of binary search tree where each node has an associated rank. The rank represents the number of nodes in the subtree rooted at that node. A balanced tree is a tree where the heights of the left and right subtrees of every node differ by at most one.
There are different types of balanced trees, such as AVL trees, red-black trees, and B-trees. AVL trees are self-balancing binary search trees where the heights of the left and right subtrees differ by at most one. Red-black trees are also self-balancing binary search trees with additional properties to ensure balance. B-trees are balanced search trees designed for efficient disk access.
