# HumanEval/20

Implement a file **`solution.py`** that completes the function below. Keep the given name and signature; your file must define it at module level.

```python
from typing import List, Tuple


def find_closest_elements(numbers: List[float]) -> Tuple[float, float]:
    """ From a supplied list of numbers (of length at least two) select and return two that are the closest to each
    other and return them in order (smaller number, larger number).
    >>> find_closest_elements([1.0, 2.0, 3.0, 4.0, 5.0, 2.2])
    (2.0, 2.2)
    >>> find_closest_elements([1.0, 2.0, 3.0, 4.0, 5.0, 2.0])
    (2.0, 2.0)
    """

You are an expert programmer. Solve the task exactly as specified. Output your solution as fenced code blocks using the required file name(s) and the exact function/type signatures requested. Prefer correctness; do not include prose outside code unless asked.

```python
from typing import List, Tuple

def find_closest_elements(numbers: List[float]) -> Tuple[float, float]:
    numbers_sorted = sorted(numbers)
    min_diff = float('inf')
    result = (0.0, 0.0)

    for i in range(len(numbers_sorted) - 1):
        current_diff = numbers_sorted[i+1] - numbers_sorted[i]
        if current_diff < min_diff:
            min_diff = current_diff
            result = (numbers_sorted[i], numbers_sorted[i+1])

    return result
```
