  1. Leaf node

    refimprove date September 2010 Image AVLtreef.svg thumb 9, 14, 19, 67 and 76 are leaf nodes. In computer science , a leaf node or external node is a node computer science node of a tree data structure that has zero child node s. Often, leaf nodes are the nodes farthest from the root node . In the Tree graph theory graph theory tree , a leaf node is a vertex of degree 1 other than the root except when the tree has only one vertex then the root, too, is a leaf . Every tree has at least one leaf. A non leaf node is called an internal node . Some trees only store data in internal nodes, though this affects the dynamics of storing data in the tree. For example, with empty leaves, one can store an empty tree with a single leaf node. However with leaves that can store data, it is impossible to store an empty tree unless one stores some kind of marker data in the leaf that signifies that the leaf is to be empty and thus the tree to be empty as well . Conversely, some trees only store data in the leaf nodes, and use the internal nodes to hold other metadata, such as the range of values in the subtree rooted at that node. This type of tree is useful for range queries. Another example of this is a parse tree . In this type of structure, the root node represents the starting symbol of a grammar, and all internal nodes represent derivations of non terminals , which continue downward until concrete symbols are established. The leafs are the actual lexical tokens of the sentence. ref Aho, Alfred V. et al. Compilers Principles, Techniques, & Tools. Boston Pearson Addison Wesley, 2007.
