WebJan 11, 2024 · Insertion sort: Insertion sort is a basic sorting algorithm that operates in the same manner that you arrange cards in your hands. The array is divided into two halves, one sorted and one not. Values from the unsorted section are selected and placed in the sorted section at the appropriate location.

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:
