|
|
|
Bubble Sort
|
|
|
Insertion Sort

|
|
None of the above

Explanation:
Detailed explanation-1: -This algorithm is called selection sort because it repeatedly selects the next-smallest element and swaps it into place.
Detailed explanation-2: -ANSWER: Selection sort Hence, we say that selection sort takes the minimum number of swaps.
Detailed explanation-3: -Which sorting algorithms may make multiple swaps per pass? Bubble sort may make multiple swaps in a single pass.
Detailed explanation-4: -The selection sort improves on the bubble sort by making only one exchange for every pass through the list.
Detailed explanation-5: -Selection sort is the algorithm which takes minimum number of swaps, and in the best case it takes ZERO (0) swaps, when the input is in the sorted array like 1, 2, 3, 4.
