What are some common sorting algorithms used in programming?

Some common sorting algorithms include Quick Sort, Merge Sort, Bubble Sort, and Insertion Sort. Would you like to know more about any specific one?

Can you explain how Quick Sort works?

Quick Sort is a divide-and-conquer algorithm. It selects a 'pivot' element and partitions the array into two sub-arrays: elements less than the pivot and elements greater than the pivot. It then recursively sorts the sub-arrays.

What are the time complexities of these sorting algorithms?

The time complexities vary: Quick Sort has an average case of O(n log n), Merge Sort is O(n log n), Bubble Sort is O(n^2), and Insertion Sort is O(n^2) in the worst case.

Which sorting algorithm is the fastest?

It depends on the context. Quick Sort is often faster in practice for large datasets, but Merge Sort is more efficient for linked lists and guarantees O(n log n) performance.
