<｜begin▁of▁sentence｜>### Instruction:
Given a path graph with 5 nodes, what are the edges of the graph's square (2nd power), where two nodes are connected in the square if and only if their shortest path in the original graph is at most 2?
### Response:
import networkx as nx

# Create a path graph with 5 nodes
G = nx.path_graph(5)

# Calculate the square (2nd power) of the graph
G2 = nx.power(G, 2)

# Print the edges of the original and squared graph
print('Original graph edges:', list(G.edges()))
print('Squared graph edges:', list(G2.edges()))
