The following pseudo‑code implements a bubble sort with an early‑exit flag: repeat swapped = false for i = 1 to n-1 if A[i] A[i+1] then swap A[i], A[i+1] swapped = true until not swapped If the array is already sorted and n = 6, how many comparisons are performed? Also, what is the maximum number of comparisons for n = 6 in the worst case? State the results and the algorithm's time‑complexity class.

Question

The following pseudo‑code implements a bubble sort with an early‑exit flag: repeat swapped = false for i = 1 to n-1 if A[i] > A[i+1] then swap A[i], A[i+1] swapped = true until not swapped If the array is already sorted and n = 6, how many comparisons are performed? Also, what is the maximum number of comparisons for n = 6 in the worst case? State the results and the algorithm's time‑complexity class.

Accepted Answer

5 comparisons (best case), 15 comparisons (worst case), O(n^2)
