<｜begin▁of▁sentence｜>### Instruction:
Given a line graph G constructed from a base graph H, how can you find the original graph H using NetworkX's inverse_line_graph function?
### Response:
import networkx as nx

# Check if a graph is a line graph
H = nx.Graph([(1, 2), (2, 3), (3, 4)])
G = nx.line_graph(H)

try:
    original_graph = nx.inverse_line_graph(G)
    print('The inverse line graph is:', original_graph.edges())
except nx.NetworkXError as e:
    print(str(e))
except nx.NetworkXNotImplemented as e:
    print('The function is not implemented for directed or multigraphs.')
