Step-by-Step Solution
Solution:
Step 1: Understand node-edge relationship
Nodes hold lists of edges to represent multiple connections.Step 2: Model two-way edges
Two-way edges require adding edges in both directions between nodes.Step 3: Evaluate options
Create nodes with lists of edges; for two-way edges, add edges in both directions correctly models nodes with multiple edges and two-way connections by adding edges both ways.Final Answer:
Create nodes with lists of edges; for two-way edges, add edges in both directions -> Option AQuick Check:
Two-way edges = edges both ways [OK]
Quick Trick: Two-way edges need two directed edges, one each way [OK]
Common Mistakes:
MISTAKES- Using single edge object for all connections
- Assuming undirected edges cover all cases
- Not linking edges to nodes
