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

Insertion Sort Complexity Time Complexity BestO(n) WorstO(n2) AverageO(n2) 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. ...

Space complexity: O(1) as it sorts in place. Basic Insertion Sort ImplementationHere's a basic implementation of insertion sort for numeric data in PHP. basic_insertion_sort.php <?php function insertionSort(array &$arr): void { $n = count($arr); for ($i = 1; $i < $n; $i++) ...
It has a space complexity ofO(1). Implementation of Insertion Sort in JavaScript Code: functioninsertionSort(arr, n) {leti, key, j;for(i =1; i < n; i++) { key = arr[i]; j = i -1;while(j >=0&& arr[j] > key) { arr[j +1] = arr...
Output: As we can see, the Insertion Sort has a space complexity ofO(1)as it does not occupy any other array of spaces to store the key rather than the1slot. So, if you are conscious about optimal space, this sort might fit well....
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...
