Question
Which of the following is not in place sorting algorithm by default?
- insertion sort
- merge sort
- quick sort
- heap sort
Solution
The sorting algorithm that is not in-place by default among the options provided is Merge Sort.
Here's why:
-
Insertion Sort: This is an in-place sorting algorithm because it only requires a constant amount O(1) of additional space.
-
Merge Sort: This is not an in-place sorting algorithm. It requires additional space proportional to the array being sorted, so its space complexity is O(n).
-
Quick Sort: This is an in-place sorting algorithm. It sorts the array by swapping elements within the array and does not require additional space.
-
Heap Sort: This is also an in-place sorting algorithm. It sorts the array by turning it into a binary heap structure, which is done in the array itself.
So, the answer is Merge Sort.
