The idea is that the nodes of the graph represent tasks and an edge from A to B indicates that A has to be performed before B. A topological sort will arrange these tasks in a sequence such that all the dependencies of a task appear earlier than the task itself. sharpclipboard

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. The following algorithms are described for a … WebA Threaded Binary Tree is a variant of a normal Binary Tree that facilitates faster tree traversal and does not require a Stack or Recursion. It decreases the memory wastage by setting the null pointers of a leaf node to the in-order predecessor or in-order successor. Recommended Topic, Binary Tree Postorder Traversal.
