Extracted Specification
An integer A (1 ≤ A ≤ 10^9).
An integer B (A ≤ B ≤ 10^9).
An integer K (1 ≤ K ≤ 100).
### Example Input:
```
3 8 2
```
### Function Signature:
Write a function f(A, B, K) that takes in the input.
```python
def f(A: int, B: int, K: int):
'''
A: an integer
B: an integer
K: an integer
'''
```
Test Case Generator
Certainly! Below is a test case generator for the given problem statement.
### Test Case Generator
```python
import random
def tcgen():
# Constraints
A = random.randint(1, 10**9)
B = random.randint(A, 10**9) # Ensure B >= A
K = random.randint(1, 100)
return A, B, K
# Example of generating a test case
if __name__ == "__main__":
A, B, K = tcgen()
print(A, B, K)
```
### Explanation
1. **A**: Randomly generate the starting integer within the range [1, 10^9].
2. **B**: Randomly generate the ending integer within the range [A, 10^9] to ensure B is always greater than or equal to A.
3. **K**: Randomly generate K within the range [1, 100].
### Sample Output Generation
To generate the sample output based on the generated test case, you can follow this logic:
```python
def generate_output(A, B, K):
numbers = list(range(A, B + 1))
smallest_k = numbers[:K]
largest_k = numbers[-K:]
result = sorted(set(smallest_k + largest_k))
return result
# Example of generating a test case and its output
if __name__ == "__main__":
A, B, K = tcgen()
print(f"Generated Test Case: A={A}, B={B}, K={K}")
output = generate_output(A, B, K)
print("Output:")
for num in output:
print(num)
```
### Explanation of Output Generation
1. **Numbers**: Create a list of numbers from A to B inclusive.
2. **Smallest K**: Extract the first K elements from the list.
3. **Largest K**: Extract the last K elements from the list.
4. **Merge and Sort**: Merge the two lists, remove duplicates using `set`, and sort the result.
5. **Print**: Print the sorted result.
By using the above functions, you can generate both the test case and the expected output to verify the correctness of your implementation.
