WebNov 7, 2024 · Function weight returns the weight of a given edge, with that edge identified by its two incident vertices. For example, calling weight (0, 4) on the graph of Figure 14.1.1 (c) would return 4. If no such edge exists, the weight is defined to be 0. So calling weight (0, 2) on the graph of Figure 14.1.1 (c) would return 0. Web1. Directed Graph (Digraph) Implementation. Following is the Java implementation of a digraph using an adjacency list: As evident from the above code, an edge is created from src to dest in the adjacency list in a digraph, and if the graph is undirected, additionally construct an edge from dest to src in the adjacency list. 2. in a dark corner movie
