algorithm - Time complexity for Shell sort? - Stack Overflow

WitrynaIt is a sorting algorithm that is an extended version of insertion sort. Shell sort has improved the average time complexity of insertion sort. As similar to insertion sort, it is a comparison-based and in-place sorting algorithm. Shell sort is efficient for medium-sized data sets. In insertion sort, at a time, elements can be moved ahead by ... Witryna15 gru 2013 · Quicksort's inner loop is very efficient, so your algorithm may also be faster than other stable sorting algorithms like mergesort, though the probability is low I guess. Drawback is, it consumes more space than mergesort (for storing indices as well). And by looking at the comparison function, I guess it will perform very poor on arrays with ... dripping hot water heater

WitrynaThe worst-case of your implementation is Θ(n^2) and the best-case is O(nlogn) which is reasonable for shell-sort. The best case ∊ O(nlogn): The best-case is when the array is already sorted. The would mean that the inner if statement will never be true, making the inner while loop a constant time operation.
