Question

Consider an array on which bubble sort is used. To which of the given elements will the bubble sort compare the element A[x] with, in a single iteration.
a. A[x+1]
b. A[x+2]
C. A[x+2x]
d. All the above

Answer 1

Answer:A[x+1]

Explanation:

Answer 2

(A) A[x+1]

In a single iteration, bubble sort compares the element A[x] with A[x+1]

Explanation:

• Bubble sort is one of the simplest sorting methods where the comparison of each element is carried out with the next element and both elements are exchanged if the element is larger than the next element.
• Bubble sort is also named as sinking sort.
• So inspecting an array of N integers, if bubble sort is implemented on it then each element will be compared with the next element to it.
• i.e. first element A[0] will be compared with the second element A[1], second element A[1] will be compared with the third element A[2], and so on.
• Hence, in bubble sort, element A[x] is compared with element A[x+1].
