Which of these algorithms compares consecutive pairs of items and swaps two items if they’re not in order?
A
Bubble sort
B
Linear search
C
Merge sort
D
Binary search
Explanation: 

Detailed explanation-1: -Bubble sort is a simple sorting algorithm that repeatedly steps through the list to be sorted, compares each pair of adjacent items and swaps them if they are in the wrong order. The pass through the list is repeated until no swaps are needed, which indicates that the list is sorted. Was this answer helpful?

Detailed explanation-2: -Bubble Sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in the wrong order.

Detailed explanation-3: -Bubble sort is a simple sorting algorithm. This sorting algorithm is comparison-based algorithm in which each pair of adjacent elements is compared and the elements are swapped if they are not in order.

Detailed explanation-4: -An advantage of merge sort over bubble sort is that it is much faster and therefore takes less time to sort large lists and lists that are more unordered. However, bubble sort can actually be quicker than merge sort on smaller lists and lists that are mostly in order.

Detailed explanation-5: -In the bubble-sorting technique, consecutive adjacent pairs of elements in the array are compared with each other. The bubble-sorting technique is the easiest sorting algorithm among others.
