Sure! Based on the given problem statement for "Cleaning Robot," we need to generate test cases automatically. Here's the Python code for generating test cases:

```python
import random

def generate_test_case():
    # Generate the initial battery points n (1 <= n <= 15)
    n = random.randint(1, 15)
    
    # All possible rooms
    rooms = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I']
    
    # Randomly select three distinct rooms for s, t, and b
    s, t, b = random.sample(rooms, 3)
    
    # Return the test case as a tuple
    return n, s, t, b

def generate_multiple_test_cases(num_cases):
    test_cases = []
    
    for _ in range(num_cases):
        test_cases.append(generate_test_case())
    
    # Add the terminating dataset
    test_cases.append((0,))
    
    return test_cases

# Generate test cases
num_cases = random.randint(1, 100)  # Number of datasets (1 <= number of datasets <= 100)
test_cases = generate_multiple_test_cases(num_cases)

# Print the generated test cases in the required format
for case in test_cases:
    print(" ".join(map(str, case)))
```

This code will generate multiple test cases for the "Cleaning Robot" problem and print them in the required format. The number of datasets is picked randomly between 1 and 100, and each dataset is generated such that:

1. `n` is an integer between 1 and 15.
2. `s`, `t`, and `b` are distinct rooms selected randomly from a list of room identifiers.

The last dataset in the output is (0,) which indicates the end of input.

Here's an example output for reference:

```
8 G A B
15 F D G
7 B F H
...
0
```

You can run this code to generate and test various scenarios for your competitive programming problem.
