"WebIn computer science, tree traversal (also known as tree search and walking the tree) is a form of graph traversal and refers to the process of visiting (e.g. retrieving, updating, or deleting) each node in a tree data structure, exactly once. Such traversals are classified by the order in which the nodes are visited. " - Graph theory order of a tree

WebThe graph theory can be described as a study of points and lines. Graph theory is a type of subfield that is used to deal with the study of a graph. With the help of pictorial representation, we are able to show the mathematical truth. The relation between the nodes and edges can be shown in the process of graph theory. WebDepth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) and explores as far as possible along each branch before backtracking. Extra memory, usually a stack, is needed to keep track of the nodes …
