From the pseudo code and the illustration above, insertion sort is the efficient algorithm when compared to bubble sort or selection sort. Instead of using for loop and present conditions, it uses a while loop
functioninsertionSort(array){leti=0letj=0for(i=1;i<array.length;i++){for(j=0;j<i;j++){if(array[i]<array[j]){const[item]=array.splice(i,1);// get the item on ith positionarray.splice(j,0,item);// insert the item on jth position}}}returnarray;}letnumbers=[10,5,6,3,2...
19. Explain the role of the outer loop in the Insertion Sort algorithm.The outer loop of Insertion Sort checks each element in the unsorted part of the array, which tells us that the entire array is ready for sorting.20. What is the role of the inner loop in Insertion Sort?
Insertion Sort Implementation To implement the Insertion Sort algorithm in a programming language, we need: An array with values to sort. An outer loop that picks a value to be sorted. For an array withnnvalues, this outer loop skips the first value, and must runn−1n−1times. ...
We have used the insertionSort() function to implement the insertion sort that accepts *array and size as arguments. The outer for loop starts with index 1 as we assume that the 0th index is already sorted. We use this element to compare with the rest of the elements of the array. The...
in the unsorted sublist and swap it with the first element of the unsorted sublist. But in the case of insertion sort, we pick the first element of the unsorted sublist and place it in its correct final position i.e. we sort the first i elements in each iteration of the outer loop. ...
Function Definition: TheinsertionSortfunction accepts a slice of integers and sorts it in ascending order using the Insertion Sort algorithm. Outer Loop: The outer loop starts from the second element (index 1) and iterates through the list. ...
In any case, like the other sort routines in this chapter, the insertion sort runs in O(N2) time for random data. For data that is already sorted or almost sorted, the insertion sort does much better. When data is in order, the condition in the while loop is never true, so it beco...
