<｜begin▁of▁sentence｜>### Instruction:
As a network scientist, you may have used the UniqueIdGenerator in networkx to assign unique identifiers to nodes in a network. Now you need to retrieve and display the reverse mapping of these identifiers back to their corresponding nodes. How can you achieve this using the networkx library?
### Response:
from networkx.utils import UniqueIdGenerator

# Initialize the UniqueIdGenerator
gen = UniqueIdGenerator()

# Generate some unique IDs
id_a = gen['object_a']
id_b = gen['object_b']
id_c = gen['object_c']

# Get the reverse mapping from IDs to objects
reverse_mapping = gen.reverse_dict()

# Display the reverse mapping
print(reverse_mapping)
