Sure! To generate test cases for the "Dropping Ink" problem, we need to create random drops of ink with their positions and sizes. Here’s a test case generator for this problem:

```python
import random

def tcgen():
    # Paper dimensions
    paper_size = 10
    
    # Number of ink drops
    num_drops = random.randint(1, 50)
    
    # Generate ink drops
    drops = []
    for _ in range(num_drops):
        x = random.randint(0, paper_size - 1)
        y = random.randint(0, paper_size - 1)
        size = random.randint(1, 3)  # Size can be 1 (Small), 2 (Medium), or 3 (Large)
        drops.append((x, y, size))
    
    return drops

# Example usage
for drop in tcgen():
    print(f"{drop[0]},{drop[1]},{drop[2]}")
```

This script generates a series of random ink drops and their properties (x, y, size). The number of drops is between 1 and 50, and the coordinates (x, y) are within the 10x10 grid. The size of each drop is randomly chosen from 1 (Small), 2 (Medium), or 3 (Large).

Here's an example of what the generator might output:

```
2,5,3
3,6,1
3,4,2
4,5,2
3,6,3
2,4,1
```

This output can be used as input to your "Dropping Ink" problem to test different scenarios.
