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. Webif insertion sort is used to sort and array of N elements that is already sorted in the right order, the number of array comparisons performed by insertion sort will be N-1 an array of 4 elements is being sorted in ascending order using the insertion sort algorithm.

WebInsertion sort is stable, for two reasons: 1. We don't swap elements if they're equal, so they'll remain in the same position relative to each other. 2.
