For Insertion Sort, there is a big difference between best, average and worst case scenarios. You can see that by running the different simulations above.The red line above represents the theoretical upper bound
Insertion Sort is used to sort large data sets less efficiently because its worst-case and average time complexity is O(n2). If the array is sorted, then its (n) time complexity. It is the best case. It does not need additional memory to sort, and therefore, the space complexity is ...
The insertion_sort_desc function sorts the array in descending order. Comparing Insertion Sort with Quick SortInsertion sort is efficient for small datasets but has a time complexity of O(n²) for larger datasets. Quick sort, on the other hand, has an average time complexity of O(n log ...
On average, each value must be compared to aboutn2n2other values to find the correct place to insert it. Insertion Sort must run the loop to insert a value in its correct place approximatelynntimes. We get time complexity for Insertion Sort: ...
The ICIS algorithm is an in-place sorting algorithm and its time complexity in average and worst cases is O (n log m), where m is less than n several times (m<; n). The proposed algorithm takes into consideration the nature of data distribution and the purpose of the application which...

However, even if we pass the sorted array to the Insertion sort technique, it will still execute the outer for loop thereby requiring n number of steps to sort an already sorted array. This makes the best time complexity of insertion sort a linear function of N where N is the number of...
