How can I implement advanced sorting algorithms in C++?

You can implement advanced sorting algorithms like quicksort, mergesort, or heapsort. Which one are you interested in?

I'd like to know more about quicksort.

Quicksort is a divide-and-conquer algorithm. It works by selecting a 'pivot' element and partitioning the array around it. Would you like a code example?

Yes, please provide a code example for quicksort.

Here's a simple implementation of quicksort in C++:

void quicksort(int arr[], int low, int high) {
    if (low < high) {
        int pi = partition(arr, low, high);
        quicksort(arr, low, pi - 1);
        quicksort(arr, pi + 1, high);
    }
}

Let me know if you need further explanation!
