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 ...
Insertion Sort OverviewInsertion sort builds the final sorted array one item at a time. It is efficient for small data sets or nearly sorted data. The algorithm works by dividing the array into sorted and unsorted parts. Time complexity: O(n²) in worst case, O(n) in best case (...
A whole bunch of sorting techniques was developed by interested individuals with the vision to ensure optimality, acceleration, and fewer spacings. In this run, the insertion sort shows the worst-case time complexity isO(n^2), whereas the best case isO(n). ...
Time Complexity Average Case On average,icomparisons are made in theithpass of insertion sort. So if there are n iterations, then the average time complexity can be given below. 1 + 2 + 3 +... +(n-1)=n*(n-1)/2 Hence the time complexity is of the order of [Big Theta]: O(n2...
Insertion Sort has a time complexity of \( O(n^2) \) in the worst case but performs better for nearly sorted datasets. Example Program for Insertion Sort Program – insertion_sort.go </> Copy package main import "fmt" // Function to implement Insertion Sort ...

Space ComplexityO(1) StabilityYes Time Complexities Worst Case Complexity:O(n2) Suppose, an array is in ascending order, and you want to sort it in descending order. In this case, worst case complexity occurs. Each element has to be compared with each of the other elements so, for every...
