To solve this problem, we need to find the common elements between two lists, ensure these elements are unique, and return them in sorted order.

### Approach
1. **Convert Lists to Sets**: By converting each list to a set, we automatically remove any duplicate elements and allow for efficient computation of common elements using set intersection.
2. **Compute Intersection**: The intersection of two sets gives us elements that are present in both sets, which corresponds to the common elements of the original lists.
3. **Sort the Result**: Convert the resulting set of common elements into a sorted list to meet the requirement of returning elements in ascending order.

### Solution Code
```python
def common(l1: list, l2: list):
"""Return sorted unique common elements for two lists.
>>> common([1, 4, 3, 34, 653, 2, 5], [5, 7, 1, 5, 9, 653, 121])
[1, 5, 653]
>>> common([5, 3, 2, 8], [3, 2])
[2, 3]
"""
return sorted(set(l1) & set(l2))
```

### Explanation
- **Conversion to Sets**: Converting `l1` and `l2` to sets removes duplicates and allows the use of set operations.
- **Intersection**: Using the `&` operator on the sets derived from `l1` and `l2` efficiently finds common elements.
- **Sorting**: The `sorted()` function converts the resulting set into a sorted list, ensuring the output is in ascending order.

This approach ensures that we efficiently find unique common elements and return them in the required sorted order.

gpto1 Here's the completed Python code for the `common` function:

```python
def common(l1: list, l2: list):
"""Return sorted unique common elements for two lists.
>>> common([1, 4, 3, 34, 653, 2, 5], [5, 7, 1, 5, 9, 653, 121])
[1, 5, 653]
>>> common([5, 3, 2, 8], [3, 2])
[2, 3]

# Convert both lists to sets to remove duplicates and allow set operations
set1 = set(l1)
set2 = set(l2)

# Find the intersection of the two sets
common_elements = set1 & set2 # or set1.intersection(set2)

# Return the sorted list of common elements
return sorted(common_elements)
```

**Explanation:**

- **Convert lists to sets:** By converting the lists `l1` and `l2` to sets (`set1` and `set2`), we eliminate any duplicate elements within each list.

- **Find common elements:** The intersection of `set1` and `set2` (`set1 & set2`) gives us the unique elements that are common to both sets.

- **Sort the result:** We convert the set of common elements back to a list and sort it using the `sorted()` function to get the final result.

**Example Usage:**

```python
print(common([1, 4, 3, 34, 653, 2, 5], [5, 7, 1, 5, 9, 653, 121]))
# Output: [1, 5, 653]

This function uses sets to remove duplicates and find the intersection of the two input lists. The resulting set of common elements is then converted to a sorted list before being returned.

This function works as follows:
1. It converts both lists to sets to eliminate duplicates and find the intersection of these sets, which gives the common elements.
2. It converts the result back to a list.
3. It sorts the list of common elements.
4. It returns the sorted list of common elements.

Qwen2-72B-Instruct Here is a possible solution for the given problem:

```python
def common(l1: list, l2: list):
return sorted(list(set(l1) & set(l2)))

print(common([1, 4, 3, 34, 653, 2, 5], [5, 7, 1, 5, 9, 653, 121])) # [1, 5, 653]
print(common([5, 3, 2, 8], [3, 2])) # [2, 3]
```

The function `common` first converts both lists to sets with `set(l1)` and `set(l2)`. The `&` operator is then used to find the intersection of these two sets, i.e., the elements that are common to both sets. This result is then converted back to a list with `list()`, and finally sorted with `sorted()`. This function will return a sorted list of the unique common elements of the two input lists.

baichuan4 To complete the Python code for the `common` function, we need to find the unique common elements between two lists and return them in a sorted order. We can achieve this by converting each list into a set, which automatically removes duplicates, and then performing an intersection of these sets. Finally, we convert the resulting set back into a list and sort it before returning. Here's how you can complete the function:

```python
def common(l1: list, l2: list):
"""Return sorted unique common elements for two lists.
>>> common([1, 4, 3, 34, 653, 2, 5], [5, 7, 1, 5, 9, 653, 121])
[1, 5, 653]
>>> common([5, 3, 2, 8], [3, 2])
[2, 3]
"""
# Convert both lists into sets to remove duplicates and perform intersection
common_elements = set(l1).intersection(set(l2))
# Convert the set of common elements back into a list and sort it
return sorted(list(common_elements))
```

This function first converts `l1` and `l2` into sets using `set(l1)` and `set(l2)`. Then, it finds the intersection of these sets with `.intersection()`, which gives us the common elements. The result is a set, so we convert it into a list with `list(common_elements)` and sort it with `sorted()` before returning. This ensures that the returned list is sorted and contains only unique common elements.

minimax To complete the function `common`, we need to find the common elements between the two lists `l1` and `l2`. We can do this by converting both lists to sets and then finding the intersection of these sets. After finding the common elements, we need to return them as a sorted list.

[2, 3]
"""
# Convert lists to sets to remove duplicates and find the intersection
common_elements = set(l1).intersection(set(l2))
# Return the sorted list of common elements
return sorted(common_elements)

# Example usage:
print(common([1, 4, 3, 34, 653, 2, 5], [5, 7, 1, 5, 9, 653, 121])) # Output: [1, 5, 653]
print(common([5, 3, 2, 8], [3, 2])) # Output: [2, 3]

This function will work as expected for the provided examples and any other pair of lists. It's worth noting that the order of the elements in the input lists does not matter, as sets do not preserve order. The `sorted` function is used to return the common elements in ascending order.
