Insertion sort performs slightly better than the previously discussed algorithms. Its complexity is O(n2). Though it has the same complexity as bubble sort and selection sort, it sorts faster than both of these in most cases. One of the best use cases for using this algorithm is to sort a dynamic collection. If you have a dynamic collection where items will keep on getting added to it at runtime, it can be sorted very efficiently by using insertion sort as and when the item reaches.
Understanding insertion sort
How the insertion sort algorithm works
The insertion sort algorithm has two subarrays (one sorted and another unsorted). Initially, the sorted subarray has only one item (the item at the 0th index) and the unsorted...
