## How do you write a bubble sort in pseudocode?

Bubble Sort Pseudocode We start with the first element and i=0 index and check if the element present at i+1 is greater then we swap the elements at index i and i+1. If above is not the case, then no swapping will take place. Now “ i ” gets incremented and the above 2 steps happen again until the array is exhausted.

## How do you write a bubble sort algorithm?

Algorithm for Bubble Sort

- algorithm Bubble_Sort(list)
- Pre: list != fi.
- Post: list is sorted in ascending order for all values.
- for i <- 0 to list:Count – 1.
- for j <- 0 to list:Count – 1.
- if list[i] < list[j]
- Swap(list[i]; list[j])
- end if.

**How do you write pseudocode for sorting?**

Selection sort pseudocode

- Find the smallest card. Swap it with the first card.
- Find the second-smallest card. Swap it with the second card.
- Find the third-smallest card. Swap it with the third card.
- Repeat finding the next-smallest card, and swapping it into the correct position until the array is sorted.

**How does a bubble sort work?**

Instead of searching an array as a whole, the bubble sort works by comparing adjacent pairs of objects in the array. If the objects are not in the correct ordered, they are swapped so that the largest of the two moves up. The swapping continues until the whole array is in the correct order.

### How is bubble sort algorithm different from modified bubble sort algorithm?

A better version of bubble sort, known as modified bubble sort, includes a flag that is set if an exchange is made after an entire pass over the array. The new best case order for this algorithm is O(n), as if the array is already sorted, then no exchanges are made.

### How is bubble sort algorithm different from modified bubble sort?

Modifying bubble sort is just a way of improving the Time Complexity in the best case of already sorted array. It works as follows: We traverse through the array, comparing and swapping the adjacent elements as we do usually do in bubble sort.

**What is bubble sort example?**

Bubble Sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in wrong order. Example: First Pass: ( 5 1 4 2 8 ) –> ( 1 5 4 2 8 ), Here, algorithm compares the first two elements, and swaps since 5 > 1.

**What is the best algorithm for sorting?**

Quicksort

Quicksort. Quicksort is one of the most efficient sorting algorithms, and this makes of it one of the most used as well. The first thing to do is to select a pivot number, this number will separate the data, on its left are the numbers smaller than it and the greater numbers on the right.

## Which is the best sorting algorithm?

Quicksort. Quicksort is one of the most efficient sorting algorithms, and this makes of it one of the most used as well. The first thing to do is to select a pivot number, this number will separate the data, on its left are the numbers smaller than it and the greater numbers on the right.

## How do you optimize bubble sort?

Bubble sort can be optimized by using a flag variable that exits the loop once swapping is done. The best complexity of a bubble sort can be O(n). O(n) is only possible if the array is sorted.

**How can I speed up my bubble sort?**

2 Answers. Change algorithm. Use MergeSort or QuickSort. BubbleSort is O(n*n).

**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,…

### What is bubble sort method?

Bubble sort, sometimes referred to as sinking sort, is a simple sorting algorithm that repeatedly steps through the list to be sorted, compares each pair of adjacent items and swaps them if they are in the wrong order.

### How to do bubble sort?

Start at index zero,compare the element with the next one (a[]&a[1](a is the name of the array)),and swap if a[]> a

**What is bubble sorting algorithm?**

In a bubble sort,we loop through an array comparing two values.
