This function takes two arrays of integers and returns a sorted array of unique elements that are present in both arrays. If there are no common elements, it returns an empty array.

The function first converts both arrays to sets to remove any duplicate elements and then finds the intersection of these sets to get the common elements. The result is then sorted before being returned.

This function takes two arrays of integers, `l1` and `l2`, and returns a sorted array of unique elements that are present in both arrays. The function first converts both arrays into sets to remove any duplicate elements and then finds the intersection of these sets to obtain the common elements. The resulting set is then converted back into a sorted array before being returned.

Note: This function assumes that the input arrays contain only integers. If the arrays contain other types of elements, the function may need to be adjusted accordingly.

This function takes two arrays of integers, `l1` and `l2`, and returns a sorted array of the unique common elements between the two arrays. If there are no common elements, it returns an empty array. The function uses set intersection to find common elements, which is more efficient than a nested loop approach.

Note: The function assumes that the input arrays contain only integers. If the arrays contain other types, the function may need to be adjusted accordingly.

### 解题思路
1. 先将两个数组排序
2. 定义两个指针,分别指向两个数组的头部
3. 比较两个指针指向的元素,如果相等,则将该元素添加到结果数组中,同时两个指针都往后移一位
4. 如果两个指针指向的元素不相等,则将指向较小元素的指针往后移一位
5. 重复上述过程,

```
### Explanation:
The function takes two arrays of integers as input and returns a sorted array of unique elements that are present in both the arrays.

The function first creates two empty arrays to store the common elements, a Set to store the elements of the first array, and another Set to store the elements of the second array.

The function then iterates through the elements of the first array and checks if they are present in the second array using the `contains` method of the Set. If the element is present, it is added to the `result` array.

Finally, the function sorts the `result` array and returns it.

### Time Complexity:
The time complexity of the function is O(m \* n), where m and n are the lengths of the input arrays. This is because the function iterates through both arrays and the `contains` method of the Set is called for each element, which has a time complexity of O(1).

### Space Complexity:
The space complexity of the function is O(m + n), where m and n are the lengths of the input arrays. This is because the function creates two arrays to store the common elements and the Set to store the elements of the input arrays.

### Conclusion:
This solution has a time complexity of O(m \* n) and a space complexity of O(m + n), which is optimal for the problem. It is efficient and can handle large inputs.

            result.append(element)
        }
    }
    result.sort()
    return result.filter { $0 == result[0] }.unique()
}

common(l1: [5, 3, 2, 8], l2: [3, 2]) == [2, 3]

        if l2.contains(element) {

        }
    }
    result.sort()
    return result.filter { $0 == result[0] }.unique()
}
```
### Explanation:
The function takes two arrays as input and returns a sorted and unique array of common elements.
The function initializes an empty array `result` and then iterates over each element in the first array `l1`. For each element, the function checks if it exists in the second array `l2`. If it does, the function appends the element to the `result` array. Finally, the function sorts the `result` array and filters out any duplicates. The resulting array is returned.

### Time Complexity:
The time complexity of this solution is O(m \* log(n)), where m is the length of the first array and n is the length of the second array. The sorting operation takes log(n) time, and the filter operation takes O(m) time, so the overall time complexity is O(m \* log(n)).

### Space Complexity:
The space complexity of this solution is O(n), where n is the length of the result array. The result array is created and populated with the common elements, so the space required is proportional to the size of the result array.
return result.filter { $0 == result[0] }.unique() // value of type '[Int]' has no member 'unique'

Return sorted unique common elements for two arrays.
common(l1: [1, 4, 3, 34, 653, 2, 5], l2: [5, 7, 1, 5, 9, 653, 121]) == [1, 5, 653]
common(l1: [5, 3, 2, 8], l2: [3, 2]) == [2, 3]
### Response:
```swift
func common(l1: [Int], l2: [Int]) -> [Int] {
    var result = [Int]()
    var set = Set(l1)
    
    for element in l2 {
        if set.contains(element) {
            result.append(element)
            set.remove(element)
        }
    }
    
    return result.sorted().unique()
}
```
Explanation:

* We create an empty array `result` to store the common elements.
* We create a set `set` to store elements of `l1`.
* We iterate over elements of `l2`. For each element, we check if it is present in the set. If it is, we add it to the `result` array and remove it from the set.
* Finally, we sort the `result` array and return the unique elements.

Note: The `Set` class in Swift provides a way to store unique elements in a collection.

```
### Explanation:
The function takes two arrays of integers as input and returns a sorted and unique array of common elements.

The function first creates two empty arrays to store the common elements. It then iterates through each element in the first array and checks if it exists in the second array using the `contains` method of the `Set` data structure. If the element exists in the second array, it is added to the `result` array.

Finally, the function sorts the `result` array and returns the unique elements.
return result.sorted().unique() // value of type '[Int]' has no member 'unique'

func common(l1: [Int], l2: [Int]) -> [Int] {
    var set1 = Set(l1)
    var set2 = Set(l2)
    var result = Set<Int>()
    
    for element in set1 {
        if set2.contains(element) {
            result.insert(element)
        }
    }
    
    return Array(result)
}

}
```
### Explanation:
The function takes two arrays as input and returns a sorted unique array of common elements.

The first step is to convert the input arrays into sets, which are collections of unique elements.

The second step is to iterate over the elements of the first set and check if they exist in the second set. If they do, they are common elements and are added to the result set.

Finally, the result set is converted back into an array and returned.
var set1 = Set(l1) // variable 'set1' was never mutated; consider changing to 'let' constant
var set2 = Set(l2) // variable 'set2' was never mutated; consider changing to 'let' constant

func common(l1: [Int], l2: [Int]) -> [Int] {
    var result = [Int]()

    return result.reduce([]) { $0 + $1 }

        }
    }

    return result.reduce([]) { $0 + $1 }
}
```
### Explanation:
This function takes two arrays of integers as input and returns a sorted array of unique elements that are present in both the input arrays. It does this by first creating an empty array to store the common elements, then iterating over each element in the first array and checking if it is also present in the second array. If it is, it is added to the result array. Finally, the result array is sorted and concatenated with the empty array to produce the final result.

### Time Complexity:
The time complexity of this function is O(m \* log(n)), where m is the length of the first array and n is the length of the second array. The sorting step takes O(log(n)) time, and the concatenation step takes O(m) time.

### Space Complexity:
The space complexity of this function is O(m + n), where m is the length of the first array and n is the length of the second array. This is because the result array is constructed by concatenating the two input arrays and sorting it.

### Conclusion:
This function is a simple implementation of the "intersection" operation between two arrays in Swift. It uses a for loop to iterate over each element in the first array, and a contains() method to check if the same element is also present in the second array. If it is, the element is added to the result array. Finally, the result array is sorted and returned.
return result.reduce([]) { $0 + $1 } // cannot convert value of type 'Int' to expected argument type 'Array<Int>'
