System: You are a helpful and precise assistant in checking the quality of the answer.
User: We would like to request your feedback on the performance of the response of the assistant to the user instruction displayed below. In the feedback, I want you to rate the quality of the response in these 3 categories according to each scoring rubric:

Logical Efficiency: Is the response logically efficient? The logic behind the response should have no redundant step, remaining simple and efficient. For tasks involving coding, the proposed solution should also consider time complexity.
Score 1: The logic behind the response is significantly inefficient and redundant, necessitating a complete reorganization of logic for clarity and efficiency.
Score 2: The logic of the response lacks efficiency and conciseness, requiring a substantial reorganization for better optimization.
Score 3: The logic of the response is not efficient enough, necessitating major edits for improved optimization.
Score 4: The logic of the response is largely efficient, but it still has some redundant steps. It could be handled from minor edits for better optimization.
Score 5: The logic of the response is optimally efficient, requiring no further optimization.
Logical Correctness: Is the final answer provided by the response logically accurate and correct for an instruction that has a deterministic answer?
Score 1: The model's final answer is completely incorrect and lacks sound reasoning.
Score 2: The model's final answer contains significant errors that critically undermine its correctness.
Score 3: The model's final answer includes inaccuracies that require considerable effort to correct.
Score 4: The model's final answer contains minor errors, which are easy to rectify and do not significantly impact its overall correctness.
Score 5: The model's final answer is completely accurate and sound.
Factuality: Did the model extract pertinent and accurate background knowledge without any misinformation when factual knowledge retrieval is needed? Is the response supported by reliable evidence or citation of the source of its information?
Score 1: The model did not extract pertinent background knowledge and provided inaccurate or misleading information. There is no support for the response through reliable evidence or source citations.
Score 2: The model extracted some relevant background knowledge but included inaccuracies or incomplete information. The response has minimal support through evidence or citations, with questionable reliability.
Score 3: The model extracted generally accurate and pertinent background knowledge, with minor inaccuracies or omissions. The response is partially supported by evidence or citations, but the support may not be comprehensive or fully reliable.
Score 4: The model extracted mostly accurate and relevant background knowledge but missed minor evidence or citations to support the response.
Score 5: The model extracted complete and accurate background knowledge without any misinformation. The response is fully supported by reliable evidence or citations that are accurate, relevant, and comprehensive in addressing the instruction.
[Instruction]
Sort an array in ascending order. You must solve the problem without using any built-in functions in O(nlog(n)) time complexity and with the smallest space complexity possible. Implementing with C++. 
The following code implementation has a time complexity of O(n^2).

#include <iostream>
using namespace std;

void bubble_sort(int nums[], int n) {
    for (int i = 0; i < n; i++) {
        for (int j = 0; j < n-i-1; j++) {
            if (nums[j] > nums[j+1]) {
                swap(nums[j], nums[j+1]);
            }
        }
    }
}

int main() {
    int nums[] = {5, 2, 9, 1, 5, 6};
    int n = sizeof(nums) / sizeof(nums[0]);

    bubble_sort(nums, n);

    for (int i = 0; i < n; i++) {
        cout << nums[i] << " ";
    }

    return 0;
}

I tried to implement the requirements of the problem without using any built-in functions in O(nlog(n)) . Can you help me solve this issue?

#include <iostream>
using namespace std;

int partition(int nums[], int low, int high) {
    int pivot = nums[high];
    int i = low - 1;

    for (int j = low; j <= high - 1; j++) {
        if (nums[j] <= pivot) {
            i++;
            swap(nums[i], nums[j]);
        }
    }
    swap(nums[i + 1], nums[high]);
    return (i + 1);
}

void quicksort(int nums[], int low, int high) {

[Ground truth Answer]
    if (low < high) {
        int pi = partition(nums, low, high);

        quicksort(nums, low, pi - 1);
        quicksort(nums, pi + 1, high);
    }
}

int main() {
    int nums[] = {5, 2, 9, 1, 5, 6};
    int n = sizeof(nums) / sizeof(nums[0]);

    quicksort(nums, 0, n - 1);

    for (int i = 0; i < n; i++) {
        cout << nums[i] << " ";
    }

    return 0;
}

[Assistant's Response]
Certainly! To achieve an efficient sorting of an array in ascending order with a time complexity of O(n log n) and minimal space complexity, you can implement the Quicksort algorithm in C++. Below is a complete implementation, including the `partition` function, the recursive `quicksort` function, and a `main` function to demonstrate usage.

```cpp
#include <iostream>
using namespace std;

// Function to partition the array
int partition(int nums[], int low, int high) {
    int pivot = nums[high]; // Choosing the last element as pivot
    int i = low - 1; // Pointer for the smaller element

    for (int j = low; j <= high - 1; j++) {
        // If current element is smaller than or equal to pivot
        if (nums[j] <= pivot) {
            i++; // Increment index of smaller element
            swap(nums[i], nums[j]); // Swap
        }
    }
    swap(nums[i + 1], nums[high]); // Swap the pivot element with the element at i + 1
    return (i + 1); // Return the partitioning index
}

// Quicksort function
void quicksort(int nums[], int low, int high) {
    if (low < high) {
        // Partitioning index
        int pi = partition(nums, low, high);

        // Recursively sort elements before and after partition
        quicksort(nums, low, pi - 1);
        quicksort(nums, pi + 1, high);
    }
}

int main() {
    int nums[] = {5, 2, 9, 1, 5, 6};
    int n = sizeof(nums) / sizeof(nums[0]);

    quicksort(nums, 0, n - 1); // Call quicksort on the entire array

    // Output sorted array
    for (int i = 0; i < n; i++) {
        cout << nums[i] << " ";
    }
    cout << endl;

    return 0;
}
```

### Explanation:
1. **Partition Function**: The `partition` function selects a pivot element (here, the last element of the array) and rearranges the array such that elements less than or equal to the pivot are on the left, and elements greater than the pivot are on the right. It returns the index of the pivot after partitioning.

2. **Quicksort Function**: The `quicksort` function sorts the array recursively. It first calls the `partition` function to divide the array into two parts and then recursively applies the same logic to the subarrays before and after the partition index.

3. **Main Function**: In the `main` function, an array is defined, and the `quicksort` function is called to sort it. The sorted array is then printed.

### Time and Space Complexity:
- **Time Complexity**: The average-case time complexity is O(n log n). However, the worst-case time complexity is O(n^2), which occurs when the smallest or largest element is always chosen as the pivot. This can be mitigated by using strategies like randomizing the pivot.
- **Space Complexity**: The space complexity is O(log n) due to the recursion stack, as Quicksort is an in-place sorting algorithm.

This implementation meets the problem's requirements by sorting the array efficiently without using any built-in sorting functions.

[The End of Assistant's Response]

Please give feedback on the assistant's responses. Also, provide the assistant with a score on a scale of 1 to 5 for each category, where a higher score indicates better overall performance. Make sure to give feedback or comments for each category first and then write the score for each category. Only write the feedback corresponding to the scoring rubric for each category. The scores of each category should be orthogonal, indicating that 'Efficiency of User Alignment' should not be considered for 'Readability of User Alignment' category, for example. 

Lastly, return a Python dictionary object that has skillset names as keys and the corresponding scores as values.
