After each iteration, one less element (the last one) is needed to be compared until there are no more elements left to be compared. Starting from the beginning of the list, compare every adjacent pair, swap their position if they are not in the right order (the latter one is smaller than the former one). More efficient algorithms such as quicksort, timsort, or merge sort are used by the sorting libraries built into popular programming languages such as Python and Java. This simple algorithm performs poorly in real world use and is used primarily as an educational tool. The algorithm, which is a comparison sort, is named for the way smaller or larger elements "bubble" to the top of the list. The pass through the list is repeated until the list is sorted. In this article, there is a clear understanding between the difference between bubble sort and selection sort.O ( n 2 ) auxiliaryīubble sort, sometimes referred to as sinking sort, is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.

Bubble Sort use exchanging method whereas selection Sort use selection method.Bubble sort is not good in terms of efficiency whereas selection sort is best for efficiency.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.
#SELECTION SORT VS BUBBLE SORT TIME COMPLEXITY CODE#
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.Įxample code for selection sort Key Differences Selection sort is a sorting algorithm that selects the largest number and swap with the last number. Selection Sortįor the better performance, bubble sort algorithm is not used, but the algorithm that is used in place of bubble sort is the selection sort algorithm. Iteration keeps on taking place until the last number iteration is called comparisons. This algorithm is not effective as compared to the other sorting algorithms. 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. If n is the number of elements in an array, then the number of iterations will be n-1. 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. 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 simplest form of sorting is bubble sort bubble sort is a sorting algorithm that compared adjacent element and then swaps. Iteration keeps on taking place until the last number iteration is called comparisons.Īdvertisement - Continue Reading Below Bubble Sort 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. 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.

The simplest form of sorting is bubble sort, bubble sort is a sorting algorithm that compared adjacent element and then swaps. 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. 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. There are many algorithms for sorting but they most famous and most used algorithms are bubble sort and selection sort. Sorting means to arrange numbers or anything in order this order can be ascending order or descending order. Computer programing is a very broad term, in computer programing, the essential concept is sorting.
