## What is the complexity of bubble sort?

The bubble sort algorithm is a reliable sorting algorithm. This algorithm has a worst-case time complexity of O(n2). The bubble sort has a space complexity of O(1). The number of swaps in bubble sort equals the number of inversion pairs in the given array.

### How do you explain bubble sort?

Bubble sort is a basic algorithm for arranging a string of numbers or other elements in the correct order. The method works by examining each set of adjacent elements in the string, from left to right, switching their positions if they are out of order.

**What is the complexity of bubble sort and how do you derive it?**

Complexity of Bubble Sort. To calculate the complexity of the bubble sort algorithm, it is useful to determine how many comparisons each loop performs. For each element in the array, bubble sort does n − 1 n-1 n−1 comparisons. In big O notation, bubble sort performs O ( n ) O(n) O(n) comparisons.

**Why is time complexity 2 on bubble sort?**

The inner loop does O(n) work on each iteration, and the outer loop runs for O(n) iterations, so the total work is O(n2).

## What is the time complexity of bubble sort in best case?

The best case for bubble sort is when the elements are already sorted. The usual implementation gives O(n^2) time complexity for best, average, worst case.

### How is time complexity defined?

Time complexity is a concept in computer science that deals with the quantification of the amount of time taken by a set of code or algorithm to process or run as a function of the amount of input. In other words, time complexity is essentially efficiency, or how long a program function takes to process a given input.

**What is the best case and worst-case complexity of bubble sort algorithm?**

Comparison with other Sorting Algorithms

Algorithm | Best Case | Worst Case |
---|---|---|

Bubble Sort | Ω(n) | Ω(n^2) |

Selection Sort | Ω(n^2) | O(n^2) |

Insertion Sort | Ω(n) | O(n^2) |

Heap Sort | Ω(n log(n)) | O(n log(n)) |

**Why bubble sort is O N Best case?**

What is the best case time complexity of bubble sort? The time complexity in the best case scenario is O(n) because it has to traverse through all the elements once to recognize that the array is already sorted.

The algorithm traverses a list and compares adjacent values, swapping them if they are not in the correct order. With a worst-case complexity of O (n^2), bubble sort is very slow compared to other sorting algorithms like quicksort.

## Why is bubble sort used in computer graphics?

Due to its simplicity, bubble sort is often used to introduce the concept of a sorting algorithm. In computer graphics it is popular for its capability to detect a very small error (like swap of just two elements) in almost-sorted arrays…

### What is the best case and Boundary Case of bubble sort?

Best case occurs when array is already sorted. Boundary Cases: Bubble sort takes minimum time (Order of n) when elements are already sorted. Due to its simplicity, bubble sort is often used to introduce the concept of a sorting algorithm.

**When does bubble sort take minimum time?**

Boundary Cases: Bubble sort takes minimum time (Order of n) when elements are already sorted. Due to its simplicity, bubble sort is often used to introduce the concept of a sorting algorithm.
