What is the key difference in approach between the Merge Sort and Quick Sort algorithms?
- Merge Sort is a comparison-based sorting algorithm that divides the array into smaller subarrays, sorts them, and then merges them back together.
- Merge Sort is an in-place sorting algorithm that rearranges elements within the original array.
- Quick Sort is a stable sorting algorithm that maintains the relative order of equal elements.
- Quick Sort uses a divide-and-conquer approach and selects a pivot element to partition the array into two subarrays.
The key difference in approach between Merge Sort and Quick Sort lies in how they divide and conquer. Merge Sort divides the array into smaller subarrays, sorts them, and then merges them back together. Quick Sort, on the other hand, selects a pivot element and partitions the array into two subarrays, which are then sorted independently. Merge Sort is not an in-place sorting algorithm, while Quick Sort typically is.
