Insertion sort is a simple sorting algorithm that works similar to the way you sort playing cards in your hands. Although it is simple to use, it is not appropriate for large data sets as the time complexity of insertion sort in the average case and worst case is o(n 2), where n is the number of items. This algorithm is a simple technique that is easy to understand and implement.

Insertion sort is used to pick any element that is not in sequence and insert it at a location where it is properly.
The following steps need to be followed:
Algorithm to sort an array of size n in ascending order: Step 1 − if it is the first element, it is already sorted. Insertion sort is less efficient than the other sorting. After every sort pass, one or more elements are inserted in a corrected location in an ordered.
The array is virtually split into a sorted and an unsorted part.
The idea behind the insertion sort is that first take one element, iterate it through the sorted array. Point the head of the given list to that of the. The steps done by this algorithm are an iterative solution of how a complex problem can be solved by repeatedly executing very simple steps. Insertion sort is a simple sorting algorithm that builds the final sorted array one item at a time.
The same approach is applied in insertion sort.
As we traverse the list, insert the current node each time, in a sorted way into the linked list. The first step is to create an empty list, which will always be sorted.
