PA of Algorithms Q87

87Assume that the algorithms considered here sort the input sequences in ascending order. If the input is already in the ascending order, which of the following are TRUE?
I. Quicksort runs in Θ(n²) time
II. Bubblesort runs in Θ(n²) time
III. Mergesort runs in Θ(n) time
IV. Insertion sort runs in Θ(n) time

Option : D
Explanation :
1. Quicksort will take worst case, if the input is in ascending order i.e Θ(n²)
2. Insertion sort runs in Θ(n) time.
