<｜begin▁of▁sentence｜>### Instruction:
Given a graph which you can read from littleballoffur4.sparse6, how can you use HybridNodeEdgeSampler to create a subgraph by alternating between random edge sampling and sampling edges from a randomly chosen node?
### Response:
import networkx as nx
from littleballoffur import HybridNodeEdgeSampler
G = nx.read_sparse6('littleballoffur4.sparse6')
sampler = HybridNodeEdgeSampler(number_of_edges=50, seed=42, p=0.5)
sampler_G = sampler.sample(G)
print(sampler_G.edges())
print(sampler_G.nodes());
