<｜begin▁of▁sentence｜>### Instruction:
Given a tournament graph with nodes labeled from 0 to 3 and directed edges (0,1), (0,2), (0,3), (1,2), (1,3), (2,3), what is the Hamiltonian path in the graph?
### Response:
import networkx as nx

# Create a tournament graph
G = nx.DiGraph([(0,1), (0,2), (0,3), (1,2), (1,3), (2,3)])

# Verify the graph is a tournament
print('Is G a tournament?', nx.is_tournament(G))

# Find a Hamiltonian path in the tournament graph
path = nx.tournament.hamiltonian_path(G)
print('Hamiltonian path in G:', path)
