Javascript program for bubble sort

Likewise, you need to repeat the iteration enough times to get it sorted fully. This means you need 2 nested loops. The inner loop is to iterate the array and the outer loop is to repeat the iteration. Please see the step-by-step example of this article. Another form of bubble sort includes starting at the end of the array and placing the smallest element first and going till the largest.

And how do you suppose you could make it run through the array again? Under what conditions should it stop? That is what I am having trouble with : — Kabir Shah. Please refer to the pseudocode implementations in Wikipedia : you need loop continuously until a condition is met no swaps happen.

Optimized Solution As we discussed the implementation of bubble sort earlier that is not optimized. Best case time complexity If the array is already sorted then it is the best-case scenario and its time complexity is O n Auxiliary Space : O 1.

This algorithm repeatedly runs until all the elements in the lists are sorted. If all the elements sorted in the list, then the algorithms end automatically.

Although the bubble sort algorithm is simple, it consumes more time comparing other sorting techniques. We have ten numbers in an array. In this case, we need to compare nine numbers so that the largest number will be sorted to the top of the array.

The reason for comparing 9 numbers instead of 10 because. They had to swap. When the below program is executed, the Bubble Sort algorithm will sort the random bar chart, which will be a different size to the order as given below in the output. Bubble Sort is the most inefficient algorithm. We should compare all the elements with each element in the array in the sorting algorithm.
