What are trees in Data Structure?
What are Trees in Data Structure? Trees are a type of data structure that represents hierarchical data. Trees are the type of non-linear data structure that consists of nodes. All the nodes of the trees are connected by an edge. In the linear data structure, the complexity of an operation increases with the increasing size of data. However, in tree data structure you can get quick access to the data which is non-linear. Trees include various types of data structures and algorithms , which makes the task performance easy and efficient. Terminologies associated with trees in the data structure are: · Node: A node in Data structure contains a value or a key and pointers to its child nodes. · Child node: A child node is connected to its parent node. The left child node has a value smaller than the parent node and the right child node has a value larger than the parent node. · Leaf nodes: Leaf nodes are also called extreme nodes. Leaf nodes do no
