<｜begin▁of▁sentence｜>### Instruction:
Given a graph with nodes {1, 2, 3, 4, 5} and edges {(1, 2), (1, 3), (2, 3), (3, 4), (3, 5)}, and a matching represented as {(1, 2), (3, 4)}, is this matching maximal in the given graph?
### Response:
import networkx as nx

# Create a graph
G = nx.Graph()

# Add edges to the graph
G.add_edges_from([(1, 2), (1, 3), (2, 3), (3, 4), (3, 5)])

# Define the matching as a set of edges
matching = {(1, 2), (3, 4)}

# Use the is_maximal_matching function to check if the matching is maximal
is_maximal = nx.is_maximal_matching(G, matching)

print('Is the matching maximal?', is_maximal)
