<｜begin▁of▁sentence｜>### Instruction:
Given a graph read from littleballoffur2.sparse6, how can you use BreadthFirstSearchSampler to sample a subgraph containing 10 nodes?
### Response:
import networkx as nx
from littleballoffur import BreadthFirstSearchSampler
G = nx.read_sparse6('littleballoffur2.sparse6')
sampler = BreadthFirstSearchSampler(number_of_nodes=10)
sampler_G = sampler.sample(G)
print(sampler_G.edges(), sampler_G.nodes())
