<｜begin▁of▁sentence｜>### Instruction:
Given a networkx erdos_renyi_graph with params n=670, p=0.2, can you use RandomNodeEdgeSampler to sample a subgraph which has 150 edges and check if the sampled graph is connected?
### Response:
import networkx as nx
from littleballoffur import RandomNodeEdgeSampler

G = nx.gnp_random_graph(n=670, p=0.2)

sampler = RandomNodeEdgeSampler(150)

sampler_G = sampler.sample(G)

# Check if the sampled graph is connected
result = nx.is_connected(sampler_G)

print(result)
