<｜begin▁of▁sentence｜>### Instruction:
Given a graph read from littleballoffur9.sparse6, how do you use ForestFireSampler to sample a subgraph with 10 nodes using a burning probability of 0.4 and a seed of 42?
### Response:
import networkx as nx
from littleballoffur import ForestFireSampler
G = nx.read_sparse6('littleballoffur9.sparse6')
sampler = ForestFireSampler(number_of_nodes=10, p=0.4, seed=42)
sampler_G = sampler.sample(G)
print(sampler_G.edges(), sampler_G.nodes())
