WebThe stack and queue are the major data structure that is used for traversing a tree. Traversal is a technique for visiting all of a tree's nodes and printing their values. Traversing a tree involves iterating over all nodes in some manner. We always start from the root (head) node since all nodes are connected by edges (links).
