Scan the array again, bubbling up the second largest element. This bubbles up the largest element to the end. In the Selection Sort, we select the smallest element and swap it with the 0th index element in the first iteration. On the other hand, selection sort works by selecting the element and swapping that particular element with the last element. This algorithm is not effective as compared to the other sorting algorithms. If n is the number of elements in an array, then the number of iterations will be n-1. Bubble Sort vs Insertion Sort . If a pair of elements is in the wrong order they are swapped to place them in the correct order. Bubble Sort use exchanging method whereas selection Sort use selection method. There is a lot of difference between bubble sort and selection sort, but if we talk about the main difference then the main difference between bubble sort and selection sort is that bubble sort is a sorting algorithm that compared adjacent element and then swaps whereas selection sort is a sorting algorithm that select largest number and swap with the last number. A stable sorting algorithm, is a sorting algorithm that retains order of records if the list contains elements with an equal value. Iteration keeps on taking place until the last number; iteration is called comparisons. In this article, we will learn how to sort elements in a list using various techniques, like Bubble Sort, Insertion Sort, and Selection Sort. Computer programing is a very broad term, in computer programing, the essential concept is sorting. In selection sort, we select one number, and that number is selected on demand for selection whether it is in ascending order or descending order. It selects the smallest element from unsorted subarray and places in the first position of that subarray (ascending order). The logic behind the bubble sort algorithm is very simple it compare the values with all other values, and find the value until the target value is found. In this article, there is a clear understanding between the difference between bubble sort and selection sort. In si… The main purpose of sorting is to make the process of searching very easy when things are sorted, searching or any other process becomes much easier. Bubble sort is not good in terms of efficiency. In the bubble sort, each element and its adjacent element is compared and swapped if required. There are many algorithms for sorting but they most famous and most used algorithms are bubble sort and selection sort. Bubble sort repetitively compares adjacent pairs of elements and swaps if necessary. It uses a nested loop to repetitively swap elements and bubble up the largest elements one by one. If n is the number of elements in an array, then the number of iterations will be n-1. Bubble sort is an iterative algorithm, using iterative, it means that this algorithm will keep on repeating or doing the sorting until it finds what the target is. If we need to find the largest number or the position of the largest number, then the position of the largest number will be the nth position. Difference Between Comparable and Comparator in Java, Difference Between Recursion and Iteration, Difference Between Insertion Sort and Selection Sort, Difference Between Quick Sort and Merge Sort, Difference Between Logical and Physical Address in Operating System, Difference Between Preemptive and Non-Preemptive Scheduling in OS, Difference Between Synchronous and Asynchronous Transmission, Difference Between Paging and Segmentation in OS, Difference Between Internal and External fragmentation, Difference Between while and do-while Loop, Difference Between Pure ALOHA and Slotted ALOHA, Difference Between Go-Back-N and Selective Repeat Protocol, Difference Between Prim’s and Kruskal’s Algorithm, Difference Between Greedy Method and Dynamic Programming. The logic behind the bubble sort algorithm is elementary it compare the values with all other values, and find the value until the target value is found. Selection sort algorithm is fast and efficient as compared to bubble sort which is very slow and inefficient. Bubble sort is a sorting algorithm that compared adjacent element and then swaps whereas selection sort is a sorting algorithm that selects the largest number and swap with the last. The following tracks the code on an arra… Bubble sort is a sorting algorithm that operates by going through the list to be sorted repeatedly while comparing pairs of elements that are adjacent. The selected element could be largest or smallest depending on the order i.e., ascending or descending. This algorithm divides the array into two parts: sorted (left) and unsorted (right) subarray. Bubble sort is an iterative algorithm, by means of iterative, it means that this algorithm will keep on repeating or doing the sorting until it finds what the target is. The complexity of bubble sort is O(n) whereas selection Sort complexity is O(n^2). Selection Sort. Sorting means to arrange numbers or anything in order; this order can be ascending order or descending order. Selection sort is a sorting algorithm that selects the largest number and swap with the last number.
