Trees are well-known as a non-linear data structure. They don’t store data in a linear way. They organize data hierarchically.
A tree is a collection of entities called nodes. Nodes are connected by edges. Each node contains a value or data or key, and it may or may not have a child node. The first node of the tree is called the root. Leaves are the last nodes on a tree. They are nodes without children.
