You have been given a Python function that returns a dictionary named `pkg_dict`. Your task is to write an efficient algorithm that takes this dictionary and performs the following operations:

1. Sort the keys of `pkg_dict` in ascending order.
2. Sort the values of `pkg_dict` in descending order.
3. Return the updated dictionary with the sorted keys and values.

Write a function `sort_dict(pkg_dict: Dict[str, int]) -> Dict[str, int]` that implements this algorithm.

**Input:**

The input parameter `pkg_dict` is a dictionary where the keys are strings and the values are integers. The dictionary will have at most 10^5 key-value pairs.

**Output:**

Return the updated dictionary after sorting its keys in ascending order and values in descending order.

**Note:**

- If the input dictionary is empty, return an empty dictionary.

**Example:**

Input:
```python
pkg_dict = {'banana': 5, 'apple': 3, 'orange': 7, 'mango': 10}
```

Output:
```python
{'apple': 10, 'banana': 3, 'mango': 7, 'orange': 5}
```

**Explanation:**

- Sorted keys: ['apple', 'banana', 'mango', 'orange']
- Sorted values: [10, 7, 5, 3]

Hence, the updated dictionary is `{'apple': 10, 'banana': 7, 'mango': 5, 'orange': 3}`.

Sure, I'd be happy to help with that. Here is a Python function `sort_dict()` that should achieve this. It uses two helper functions, `sort_keys()` and `reverse_values()`, to sort the keys and values, respectively.

```python
def sort_dict(pkg_dict: Dict[str, int]) -> Dict[str, int]:
    if not pkg_dict:
        # If dictionary is empty, return empty dictionary.
        return {}

    # Sort keys in ascending order.
    pkg_dict = sorted(pkg_dict.keys())

    # Reverse values in descending order.
    pkg_dict = {k: v for k, v in reversed(sorted(pkg_dict.items(), key=lambda x: x[1]))}

    return pkg_dict

def sort_keys(lst):
    return sorted(lst)

def reverse_values(lst):
    return sorted(lst, reverse=True)

# Example usage:
pkg_dict = {'banana': 5, 'apple': 3, 'orange': 7, 'mango': 10}
sorted_pkg_dict = sort_dict(pkg_dict)
print(sorted_pkg_dict)  # Output: {'apple': 10, 'banana': 7, 'mango': 5, 'orange': 3}
```

I'm sorry for the confusion, but it's important to note that dictionaries in Python (version 3.7 and later) maintain the insertion order, not the sorted order. This means that you can't sort the keys and values independently and maintain their correspondence in the dictionary.

However, if you want to sort the keys and values separately and pair them up regardless of their original correspondence, you can do so, but please be aware that this might not be a useful operation in many contexts. Here's how you could do it:

```python
def sort_dict(pkg_dict: Dict[str, int]) -> Dict[str, int]:
    sorted_keys = sorted(pkg_dict.keys())
    sorted_values = sorted(pkg_dict.values(), reverse=True)
    return dict(zip(sorted_keys, sorted_values))
```

In this function, `sorted_keys` are the keys of `pkg_dict` sorted in ascending order, and `sorted_values` are the values of `pkg_dict` sorted in descending order. The `zip` function is used to pair up the sorted keys and values, and `dict` is used to create a new dictionary from these pairs.

Again, please note that this function does not maintain the original correspondence between keys and values in the dictionary. If you need to maintain this correspondence while sorting, you would need to sort either the keys or the values, but not both.
