Problem p00101 - Generation 2

Orig Description

Aizu PR
An English booklet has been created for publicizing Aizu to the world.
When you read it carefully, you found a misnomer (an error in writing) on the last name of Masayuki Hoshina, the lord of the Aizu domain. The booklet says "Hoshino" not "Hoshina".
Your task is to write a program which replace all the words "Hoshino" with "Hoshina". You can assume that the number of characters in a text is less than or equal to 1000.
Input
The input consists of several datasets. There will be the number of datasets n in the first line. There will be n lines. A line consisting of english texts will be given for each dataset.
Output
For each dataset, print the converted texts in a line.
Sample Input
3
Hoshino
Hashino
Masayuki Hoshino was the grandson of Ieyasu Tokugawa.
Output for the Sample Input
Hoshina
Hashino
Masayuki Hoshina was the grandson of Ieyasu Tokugawa.

Extracted Specification

An integer n (1 ≤ n ≤ 1000), representing the number of datasets.
A list of n strings, each string's length is between 1 and 1000 characters.

### Example Input:

```
3
Hoshino
Hashino
Masayuki Hoshino was the grandson of Ieyasu Tokugawa.
```

### Function Signature:
Write a function f(n, datasets) that takes in the input.
def f(n: int, datasets: List[str]):
    ''' 
    n: an integer 
    datasets: a list of strings 
    '''

Test Case Generator

Sure! Let's write a test case generator for the given problem statement. The generator will produce multiple datasets, each containing a line of text that may include the word "Hoshino", which needs to be replaced with "Hoshina".

Here's the test case generator code for the given problem:

```python
import random
import string

def generate_random_text(length):
    """Generates a random string of the specified length."""
    parts = []
    while length > 0:
        word_length = random.randint(1, min(10, length))
        word = ''.join(random.choices(string.ascii_letters + ' ', k=word_length))
        parts.append(word)
        length -= word_length
    return ''.join(parts).strip()

def tcgen():
    # Number of datasets
    n = random.randint(1, 10)
    
    datasets = []
    for _ in range(n):
        # Decide if "Hoshino" should be included in the text
        include_hoshino = random.choice([True, False])
        
        if include_hoshino:
            length = random.randint(1, 1000 - len("Hoshino"))
            position = random.randint(0, length)
            text = generate_random_text(position) + "Hoshino" + generate_random_text(length - position)
        else:
            length = random.randint(1, 1000)
            text = generate_random_text(length)
        
        datasets.append(text)
    
    return n, datasets

# Example usage
if __name__ == "__main__":
    n, datasets = tcgen()
    print(n)
    for text in datasets:
        print(text)
```

### Explanation:

- `generate_random_text(length)`: This helper function generates a random string of the specified length using letters and spaces. It breaks the text into words of random lengths to simulate more realistic sentences.
- `tcgen()`: This function generates the test cases:
  - It first selects a random number `n` (1 to 10) representing the number of datasets.
  - For each dataset, it decides randomly whether to include the word "Hoshino".
  - If "Hoshino" is included, it constructs a string of random text with "Hoshino" inserted at a random position.
  - If "Hoshino" is not included, it generates a random text of up to 1000 characters.
  - The generated text is appended to the list of datasets.
- Finally, it returns the number of datasets and the list of datasets.

You can run this script to generate test cases for the problem statement. The output will be the number of datasets followed by the text for each dataset. Use these test cases to test your solution to the problem.
