WebInsertionSort performs better for input with many duplicates because it can skip many comparisons due to the presence of equal elements. In contrast, the other sorting algorithms need to perform many comparisons, making them slower than InsertionSort. 3) explain how quicksort behaved in special cases.

WebThe Insertion Sort ¶ The insertion sort ... The maximum number of comparisons for an insertion sort is the sum of the first $n-1$ integers. Again, this is $O(n^{2})$. However, in the best case, only one comparison needs to be done on each pass. This would be the case for an already sorted list. WebFor an array of size 4, you need to sort an array of size 3, and do 3 more comparisons. For an array of size X, you need to sort an array of size x-1 and do x-1 more comparisons.
