    Python best solution

    If you’re looking for solutions to the 3-month preparation kit in either Python or Rust, you can find them below: my solutions 

    def closest_numbers(arr):
    # Time complexity: O(n*log(n))
    # Space complexity (ignoring input): O(n)
    arr.sort()
    minimum_diff = arr[1] - arr[0]
    pairs = [arr[0], arr[1]]
    for index in range(2, len(arr)):
        if (arr[index] - arr[index - 1]) == minimum_diff:
            pairs.append(arr[index - 1])
            pairs.append(arr[index])
        if (arr[index] - arr[index - 1]) < minimum_diff:
            minimum_diff = arr[index] - arr[index - 1]
            pairs = [arr[index - 1], arr[index]]

    return pairs
