Sure! The task is to create a test case generator for the problem where we need to find the minimum possible value displayed on the board after a series of operations. Below is a Python function that generates random test cases for this problem:

```python
import random

def tcgen():
    N = random.randint(1, 10)  # N is between 1 and 10 inclusive
    K = random.randint(1, 10)  # K is between 1 and 10 inclusive
    
    return N, K

# Example of generating and printing a test case
N, K = tcgen()
print(N)
print(K)
```

### Explanation

- `N` represents the number of operations to be performed and can be any integer between 1 and 10 inclusive.
- `K` represents the value by which the number on the board increases when operation B is performed and can be any integer between 1 and 10 inclusive.

This function will generate random values for `N` and `K` within the specified constraints. You can call this function to generate test cases for your problem.

### Example Output

Here are some example outputs you might get from running the `tcgen` function:

```
3
7
```

```
10
2
```

You can use these random generated test cases to test your solution to the problem.
