Question

suppose you have the following list of numbers to sort: [19, 7, 9, 1, 3, 10, 13, 15, 8, 12] which list represents the list after the first step of a bubble sort?

Answer 1

After the first step of a bubble sort, the given list [19, 7, 9, 1, 3, 10, 13, 15, 8, 12] becomes [7, 19, 9, 1, 3, 10, 13, 15, 8, 12] because the first two elements are compared and swapped.

Step-by-step explanation:

The question asks which list represents the numbers after the first step of a bubble sort. Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order.

The list given is [19, 7, 9, 1, 3, 10, 13, 15, 8, 12]. After the first pass, the algorithm would have compared and swapped the first two elements if necessary. In this case, 19 is greater than 7, so after the first step of the bubble sort, the list would be [7, 19, 9, 1, 3, 10, 13, 15, 8, 12].
