Why does an insertion

Insertion really means that something has been stuck in there. And again, as a geneticist, when we think of an insertion, we think of a piece of DNA, and that can be small or large, being stuck in at a place where it really doesn't belong. So an insertion of just one base pair could lead to something that we call a frameshift. It shifts the reading of the three-base pair code and by that can throw off the entire protein, and by that can lead, for example, to a birth defect.

Even though insertion sort is efficient, still, if we provide an already sorted array to the insertion sort algorithm, it will still execute the outer for loop, thereby requiring n steps to sort an already sorted array of n elements, which makes its best case time complexity a linear function of n.

Wherein for an unsorted array, it takes for an element to compare with all the other elements which mean every n element compared with all other n elements. Thus, making it for n x n, i. One can also take a look at other sorting algorithms such as Merge sort, Quick Sort, Selection Sort , etc. Average Time Complexity [Big-theta]: O n 2. Sign Up using. Log In using. Toggle navigation.
