In each iteration, the comparison takes place up to the last unsorted element. The same process goes on for the remaining iterations.ДЄfter each iteration, the largest element among the unsorted elements is placed at the end. The compare time and other running time can be ignored.

And obviously reading time is less than writing time even in memory. but when using bubble sort, it swaps almost n (n-1). When using selecting sort it swaps n times at most.

The above process goes on until the last element. Bubble sort uses more swap times, while selection sort avoids this.

Now, compare the second and the third elements.

If the first element is greater than the second element, they are swapped.

Starting from the first index, compare the first and the second elements.

Suppose we are trying to sort the elements in ascending order. Just like the movement of air bubbles in the water that rise up to the surface, each element of the array move to the end in each iteration. Total comparisons in Bubble sort is: n ( n 1) / 2 n 2 n Best case 2: O (n ) Average case : O (n2) Worst case : O (n2) 3. Recall the list which had elements 5, 3, 4, 2 in it. Time Complexity of Bubble Sort : The complexity of sorting algorithm is depends upon the number of comparisons that are made. Two elements are said to be out-of-order if they do not follow the desired order. It works on the idea of repeatedly comparing the adjacent elements, from left to right, and swapping them if they are out-of-order. Majorly insertion sort and selection sort can be differentiated by the method they use to sort the data. Insertion sort and selection sort are the techniques used to sort the data.

Decrease Key and Delete Node Operations on a Fibonacci HeapД«ubble sort is a sorting algorithm that compares two adjacent elements and swaps them until they are not in the intended order. Bubble sort, also known as sinking sort, is the easiest sorting algorithm. Selection Sort, Selection Sort: Given a list, take the current element and exchange it with the smallest element on the right hand side of the current element.
