I'm lead to believe that quick sort should be faster than insertion sort on a medium size unorderd int array. … WebOct 4, 2009 · Having an unstable sort algorithm means that you have to come up with all sorts of 'magic' to sensibly sort data with multiple criteria, rather than then simply being able to chain sort calls - in timsort if you want to sort by D.O.B and then name, you simply sort by name first, and then D.O.B. You can't do that with quicksort – Tony Suffolk 66

WebMar 12, 2024 · The time complexity is generally expressed as a function of the size of the input. So if the size of the input doesn't vary, for example if every list is of 256 integers, the time complexity will also not vary and the time complexity is therefore O (1). This would be true of any algorithm, such as sorting, searching, etc. Share Cite WebDec 14, 2024 · Therefore overall time complexity of the insertion sort is O (n + f (n)) where f (n) is inversion count.

Therefore, taking advantage of this fact, we can apply a method similar to the merge sort technique. WebTime Complexity: Worse case: O(n2) When we apply insertion sort on a reverse-sorted array, it will insert each element at the beginning of the sorted subarray, making it the worst time complexity of insertion sort. Average case: O(n2) When the array elements are in random order, the average running time is O(n2 / 4) = O(n2). Best case: O(n)
