Insertion sort - Wikipedia
https://en.wikipedia.org/wiki/Insertion_sort
WebThe simplest worst case input is an array sorted in reverse order. The set of all worst case inputs consists of all arrays where each element is the smallest or second-smallest of the elements before it. In these cases every iteration of the inner loop will scan and shift the entire sorted subsection of the array before inserting the next element.

WebDec 9, 2021 · The worst-case (and average-case) complexity of the insertion sort algorithm is O (n²). Meaning that, in the worst case, the time taken to sort a list is proportional to the square of the number of elements in the list. The best-case time complexity of insertion sort algorithm is O (n) time complexity.
