Selection Sort … Web"The quickSort function should recursively sort the subarray array[p..r]." If p = r then you have a one element array that is, by definition, already sorted. So, you only need to sort subarrays that have more than one element. How many elements does array[p..r] have ? It has r-p+1 elements. So we need to sort when r-p+1 > 1 Which is equivalent to: ipsy like subscriptionsWebInsertion sort's typical runtime is O (N^2) So the total number of comparisons is proportional to (N−1)⋅ (N/2) In the worst case, assuming each comparison takes 1 µs, how long will insertion sort algorithm take to sort a list of 10 elements? 45 orchard rental properties

"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.
