Question

Sometimes we need to reorder lists based on certain conditions. What type of sorting algorithm finds the minimum value in the list and swaps it with the value in the first position, then repeats these steps for the remainder of the list?

a) Bubble sort
b) Selection sort
c) Insertion sort
d) Merge sort

Answer 1

Selection sort finds the minimum value in the list and swaps it with the value in the first position, repeating these steps for the remainder of the list.

Step-by-step explanation:

The type of sorting algorithm that finds the minimum value in a list and swaps it with the value in the first position, repeating these steps for the remainder of the list, is Selection sort.

This algorithm works by selecting the smallest unsorted element and swapping it with the leftmost unsorted element. It continues this process until the entire list is sorted.

For example, if we have a list of numbers: 5, 2, 8, 1, 9. Selection sort would start by selecting 1 (the minimum) and swapping it with 5 to get 1, 2, 8, 5, 9. It would then select the next minimum (2) and swap it with 5 to get 1, 2, 8, 5, 9. The process continues until the list is sorted.
