Binary Search Trees (BST) are data structures that can be represented by the emoji description "🌳👹🌲". The 🌳 represents the root of the tree, while 👹 symbolizes the internal nodes or branches. Each branch has a left and right subtree, denoted by the surrounding 🌲 emojis. BSTs have a specific property where the value of each node in the left subtree is less than the value of its parent node, and the value of each node in the right subtree is greater. This property allows for efficient searching, insertion, and deletion operations in BSTs.
