AVL tree

An AVL tree is a type of special tree that is used to store and organize data. It is similar to a regular tree except that it is balanced. This means that it is always arranged in a way that makes it easy to look up information quickly and efficiently. To do this, the tree arranges the data in levels, with some data higher up, and some data lower down. This makes it so that when you want to look up something, you don't have to search through all of the data, but can go directly to the part that has what you are looking for. This makes it much faster to find things and is why AVL trees are used in computers and databases.
