# How does bubble sort stop?

## How does bubble sort stop?

The best case for bubble sort occurs when the list is already sorted or nearly sorted. In the case where the list is already sorted, bubble sort will terminate after the first iteration, since no swaps were made.

Why is bubble sort so bad?

Bubble Sort is one of the most widely discussed algorithms, simply because of its lack of efficiency for sorting arrays. If an array is already sorted, Bubble Sort will only pass through the array once (using concept two below), however the worst case scenario is a run time of O(N²), which is extremely inefficient.

How is bubble sort stable?

Bubble sort is a stable algorithm. A sorting algorithm is said to be stable if two objects with equal keys appear in the same order in sorted output as they appear in the input array to be sorted.

### How long does bubble sort take?

A desktop PC these days can do a billion (109) little things in about 5 seconds. A bubble sort on 106 random ints requires about 1012 little things, or about 5000 seconds = 83 minutes. This could be off by a factor of 4 or so either way.

When should I stop using bubble sort?

When the end of the array is reached, the bubble sort algorithm will returns to element one and starts the process all over again. So, when will the bubble sort algorithm stop? The bubble sort algorithm knows when it’s finish when there are no more “swaps”.

Where is bubble sort used in real life?

Some of the best examples of real-world implementation of the same are: Bubble sorting is used in programming TV to sort channels based on audience viewing time! Databases use external merge sort to sort sets of data that are too large to be loaded entirely into memory!

#### What is the best case of bubble sort?

n
Bubble sort/Best complexity

How many passes does bubble sort need?

Three passes will be required; First Pass.

Why is bubble sort on 2?

Pretty much N is a representation of all the items in the loop kind of like 1,2,3… N. So it is simply representing a number not how many times a loop, loops. This is another version to speed up bubble sort, when we use just a variable swapped to terminate the first for loop early.

## What is a bubble sort and how does it work?

Bubble sort is a sorting algorithm that works by repeatedly stepping through lists that need to be sorted, comparing each pair of adjacent items and swapping them if they are in the wrong order. This passing procedure is repeated until no swaps are required, indicating that the list is sorted.

What is the worst case of bubble sort?

The Bubble Sort Algorithm. The absolute worst case for bubble sort is when the smallest element of the list is at the large end. Because in each iteration only the largest unsorted element gets put in its proper location, when the smallest element is at the end, it will have to be swapped each time through the list,…

How does the bubble sort actually work?

In Bubble Sort,the algorithm will take the 1 st element of the array and compare the value with the element next to it in the array.

• If the 1 st element is larger than the 2 nd,then the element will swap the positions.
• If it doesn’t satisfy the condition,then the algorithm will compare the 2 nd element with 3 rd
• ### What are the disadvantages of bubble sort?

The primary advantage of the bubble sort is that it is popular and easy to implement. The main disadvantage of the bubble sort is the fact that it does not deal well with a list containing a huge number of items. In the bubble sort, elements are swapped in place without using additional temporary storage.
