What is a leaf node?
A node that does not have any child node is called a leaf node.
Sometimes in this case if there is a single node (A) present in the tree then that node is also called a leaf node because of no child node connected to it. There is nothing connected to a leaf node further which is the endmost node of a tree in a direction.
What are the different types of Nodes in a Tree
Trees are nonlinear data structures that organize data hierarchically and in a recursive manner.
It is a method of organizing and storing data in the computer in a way that makes it more effective to use. Nodes in the graph are connected via edges. It has different types of nodes which are called parent node, child node, leaf node, etc.
