<｜begin▁of▁sentence｜>### Instruction:
Given a networkx erdos_renyi_graph with params n=900, p=0.06, how can you use RandomWalkWithRestartSampler to sample a subgraph of 30 nodes and find a dominating set for the graph G?
### Response:
```python
import networkx as nx
from littleballoffur import RandomWalkWithRestartSampler

G = nx.gnp_random_graph(n=900, p=0.06)

sampler = RandomWalkWithRestartSampler(30)

sampler_G = sampler.sample(G)

result = nx.dominating_set(sampler_G)

print(result)
```
