Although somewhat slower in practice on most machines than agood implementation of quicksort, it has the advantage of a worst-case¿(n log n) runtime. Heapsort is an in-place algorithm, but is not astable sort.…

It is much less efficient onlarge lists than more advanced algorithms such as quicksort, heapsortor merge sort. However, insertion sort provides several advantages:simple implementation, efficient for (quite) small data sets, adaptivei.e. efficient for data sets that are already substantially sorted: thetime complexity is O(n + d), where d is the number of inversions, moreefficient in practice than most other simple quadratic (i.e. O(n2))algorithms such as selection sort or bubble sort: the average runningtime is n2/4[citation needed], and the running time is linear in thebest case, stable, i.e. does not change the relative order of elementswith equal keys, in-place, i.e. only requires a constant amount O(1) ofadditional memory space, online, i.e. can sort a list as it receives it.Most humans when sorting-ordering a deck of cards, for example-use amethod that is similar to insertion sort.…
