<｜begin▁of▁sentence｜>### Instruction:
As a Feng Shui Consultant, you may be interested in applying the principles of feng shui to design and arrange a large office space for optimal energy flow, balance, and harmony. Suppose you have a 1000-node network representing the layout of the office, with connections between nodes occurring with a probability of 0.3. Using the NonBackTrackingRandomWalkSampler tool, you want to sample a subgraph with 200 nodes to evaluate whether the layout promotes connectedness, a key aspect of optimal energy flow and harmony in the office environment.
### Response:
import networkx as nx
from littleballoffur import NonBackTrackingRandomWalkSampler

G = nx.gnp_random_graph(n=1000, p=0.3)

sampler = NonBackTrackingRandomWalkSampler(200, seed=10)

sampler_G = sampler.sample(G)

result = nx.is_connected(sampler_G)

print(result)
