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 ...

WebDFS and BFS implementations. 1. DFS implementation. Below are examples of pseudocode and Python code implementing DFS both recursively and non-recursively.
