<｜begin▁of▁sentence｜>### Instruction:
Given a graph with edge set [(0, 1), (1, 2), (2, 0)], compute and display the adjacency spectrum (eigenvalues of the adjacency matrix) of the graph.
### Response:
import networkx as nx
import numpy as np

# Create a graph
G = nx.Graph()
G.add_edges_from([(0, 1), (1, 2), (2, 0)])

# Compute the adjacency spectrum (eigenvalues of the adjacency matrix)
spectrum = nx.adjacency_spectrum(G)

print('The adjacency spectrum of the graph:', np.round(spectrum, 2))
