What are some common algorithms and their associated data structures?

Common algorithms include sorting algorithms like QuickSort and MergeSort, and searching algorithms like Binary Search. They often use data structures like arrays, linked lists, and trees.

Can you explain how QuickSort works?

QuickSort 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 data structure does QuickSort use?

QuickSort primarily uses arrays for its implementation, but it can also be applied to linked lists.

Are there any advantages of using MergeSort over QuickSort?

Yes, MergeSort is stable and has a guaranteed time complexity of O(n log n), making it more predictable for large datasets, while QuickSort can degrade to O(n²) in the worst case.
