<｜begin▁of▁sentence｜>### Instruction:
Given a graph that is known to be a line graph with edge set [(1, 2), (2, 3), (3, 4), (4, 5)], what is the original graph for which this is the line graph?
### Response:
import networkx as nx

# Create a graph that is a line graph
L = nx.Graph()
L.add_edges_from([(1, 2), (2, 3), (3, 4), (4, 5)])

# Use the inverse_line_graph function
try:
    H = nx.inverse_line_graph(L)
    print('Nodes:', H.nodes())
    print('Edges:', H.edges())
except nx.NetworkXError as e:
    print(e)
except nx.NetworkXNotImplemented as e:
    print('The function is not implemented for directed or multigraphs.')
