<｜begin▁of▁sentence｜>### Instruction:
Given a directed graph with edges ('A', 'B') weight 2, ('B', 'C') weight 1, and ('A', 'C') weight 3, and a flow dictionary {'A': {'B': 1, 'C': 0}, 'B': {'C': 1}}, what is the total cost of the flow?
### Response:
import networkx as nx

# Create a DiGraph
G = nx.DiGraph()

# Add edges with weights
G.add_edge('A', 'B', weight=2)
G.add_edge('B', 'C', weight=1)
G.add_edge('A', 'C', weight=3)

# Define a flow dictionary
flowDict = {'A': {'B': 1, 'C': 0}, 'B': {'C': 1}}

# Compute the cost of the given flow
flow_cost = nx.cost_of_flow(G, flowDict)
print('The cost of the flow:', flow_cost)
