WebDFS Traversal of a Tree Using Recursion. A tree is a non-linear data structure, which consists of nodes and edges that represent a hierarchical structure. It is a connected graph with no cycles. A tree with “n” nodes should always contain “n-1” edges. Tree traversal is one of the most basic requirements for dealing with different types ...
