<｜begin▁of▁sentence｜>### Instruction:
If you have a set of items ('apple', 'banana', 'cherry') and their respective predefined IDs (101, 202, 303), how can you use the UniqueIdGenerator.__setitem__ method to override these IDs, and what would be the unique ID generated for a new item 'orange'?
### Response:
from networkx.utils import UniqueIdGenerator

# Create a UniqueIdGenerator instance
uid_gen = UniqueIdGenerator()

# Assume we have some items with predefined IDs
predefined_ids = {'apple': 101, 'banana': 202, 'cherry': 303}

# Override the IDs for the items using the __setitem__ method
for item, id in predefined_ids.items():
    uid_gen[item] = id

# Generate a unique ID for a new item that is not in predefined_ids
new_item_id = uid_gen['orange']

print(f'The unique ID for orange is: {new_item_id}')

# Print the current state of the unique ID generator
print(f'Current state: {uid_gen}')
