tree data structure
A tree data structure is a hierarchical data structure that consists of nodes connected by edges. It resembles a tree with a single root node and multiple child nodes. Each node can have zero or more child nodes, forming a branching structure. The nodes in a tree data structure are organized in levels, starting from the root node at level 0 and moving down to the leaf nodes at the lowest level. This data structure is often used for storing and organizing data in a hierarchical manner, enabling efficient searching, insertion, and deletion operations.
