<｜begin▁of▁sentence｜>### Instruction:
Given a networkx erdos_renyi_graph with params n=960, p=0.4, can you use DepthFirstSearchSampler to sample a subgraph which has 9 nodes and compute the chain decomposition of the sampled graph?
### Response:
import networkx as nx
from littleballoffur import DepthFirstSearchSampler

G = nx.gnp_random_graph(n=960, p=0.4)

sampler = DepthFirstSearchSampler(9, seed=20)

sampler_G = sampler.sample(G)

result = nx.chain_decomposition(sampler_G)

print(result)
