Which of the following is not in place sorting algorithm by default?ans.heap sortmerge sortinsertion sortquick sort Previous Marked for Review Next

The sorting algorithm that is not in-place by default among the options provided is Merge Sort.

Here's why:

1. Heap Sort: This is an in-place sorting algorithm because it only uses a constant amount of additional space.

2. Merge Sort: This is not an in-place sorting algorithm by default. It requires additional space proportional to the input size for the merged output, hence it does not meet the in-place criteria (which requires a constant, small amount of extra space).

3. Insertion Sort: This is an in-place sorting algorithm because it only requires a constant amount of additional space.

4. Quick Sort: This is also an in-place sorting algorithm because, like Heap Sort and Insertion Sort, it only requires a constant amount of additional space.
