What are some examples of algorithms in C++?

Can you give me some examples of algorithms implemented in C++?

Sure! Some common algorithms in C++ include sorting algorithms like Quick Sort and Merge Sort, and searching algorithms like Binary Search.

How does Quick Sort work?

Quick Sort is a divide-and-conquer algorithm. It selects a 'pivot' element and partitions the array into two sub-arrays according to whether elements are less than or greater than the pivot.

Can you show me a simple implementation of Merge Sort?

Absolutely! Here's a simple implementation of Merge Sort in C++:

void merge(int arr[], int left, int mid, int right) {
    // Merge function implementation
}

void mergeSort(int arr[], int left, int right) {
    // Merge Sort implementation
}

Let me know if you need the full code!

What are the time complexities of these algorithms?

Quick Sort has an average time complexity of O(n log n) and a worst-case of O(n²). Merge Sort consistently has a time complexity of O(n log n).
