How can I optimize sorting algorithms in C++?

To optimize sorting algorithms in C++, you can consider using more efficient algorithms like QuickSort or MergeSort, and also implement techniques like tail recursion and in-place sorting.

What are the differences between QuickSort and MergeSort?

QuickSort is generally faster for large datasets due to its divide-and-conquer approach, while MergeSort is stable and works well for linked lists.

Can you give me an example of implementing QuickSort in C++?

Sure! 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);
    }
}

What are some common pitfalls when optimizing sorting algorithms?

Common pitfalls include not considering the input data characteristics, using algorithms with poor worst-case performance, and neglecting memory usage.
