<｜begin▁of▁sentence｜>### Instruction:
Given a graph read from the file 'littleballoffur1.sparse6', how can you use BreadthFirstSearchSampler to sample a subgraph with 10 nodes?
### Response:
import networkx as nx
from littleballoffur import BreadthFirstSearchSampler
G = nx.read_sparse6('littleballoffur1.sparse6')
sampler = BreadthFirstSearchSampler(number_of_nodes=10)
sampled_graph = sampler.sample(G)
print(sampled_graph.edges(), sampled_graph.nodes())
