WebMar 29, 2024 · A graph is a data structure that consists of the following two components: 1. A finite set of vertices also called as nodes. 2. A finite set of ordered pair of the form (u, v) called as edge. The pair is ordered because (u, v) is not the same as (v, u) in case of a directed graph (di-graph). WebJan 2, 2024 · If the graph is a tree, this process should eliminate all nodes from the node counts (i.e. they will all be flagged as leaves at some point).
