QuestionWhich of these sorting algorithms is an internal sort: Bubble sort, Merge sort, or Multiway merging?
Studdy Solution
STEP 1
Assumptions1. We are considering the standard definitions of Bubble sort, Merge sort, and Multiway merging.
. An internal sort is a type of sorting algorithm that only requires a fixed amount of additional space (typically O(1)) and all the operations are performed in the main memory.
3. An external sort is a type of sorting algorithm that requires large amounts of additional space (typically more than O(1)) and some operations are performed outside the main memory.
STEP 2
We know that Bubble sort is an internal sort because it only requires a single additional memory space for temp variable during the swap operation. So, Bubble sort is an internal sort.
STEP 3
Merge sort is not an internal sort. It is an external sort because it requires additional space proportional to the number of elements being sorted. This is because Merge sort divides the array into two halves, sorts them separately, and then merges them. This process of dividing and merging requires additional space.
STEP 4
Multiway merging is also not an internal sort. It is an external sort because it involves merging of more than two sorted files. This requires additional space to hold the sorted files and the merged result.
So, the only internal sort among the given options is Bubble sort.
