## How much time 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.

## How do you find the time complexity of a selection sort?

The basic operation for this algorithm is the comparison at line 5, in the inner loop. Both loops are executed ≈ n times, i.e. the basic operation is executed n*n times ≈ n^2. The time complexity for selection sort is O(n^2). It is same for worst best and average cases.

What is the order of complexity in bubble sort in worst case?

Bubble sort is an in-place sorting algorithm. The worst case time complexity of bubble sort algorithm is O(n2). The space complexity of bubble sort algorithm is O(1). Number of swaps in bubble sort = Number of inversion pairs present in the given array.

How many passes does bubble sort need?

Three passes will be required; First Pass.

### What is the time complexity of the selection sort algorithm?

In computer science, selection sort is an in-place comparison sorting algorithm. It has an O(n2) time complexity, which makes it inefficient on large lists, and generally performs worse than the similar insertion sort.

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

Recall that if the random element is placed at the end, bubble sort loses its efficiency because each element greater than it must bubble all the way up to the top. The absolute worst case for bubble sort is when the smallest element of the list is at the large end.

What is the complexity of this bubble sort algorithm?

The space complexity for Bubble Sort is O (1) , because only a single additional memory space is required i.e. for temp variable. Also, the best case time complexity will be O (n), it is when the list is already sorted. Following are the Time and Space complexity for the Bubble Sort algorithm.

Is bubble sort the slowest sorting algorithm?

The speed of any particular sorting algorithm depends on a few different factors such as input order and key distribution. In many cases bubble sort is pretty slow, but there are some conditions under which it’s very fast. There’s a great sorting algorithm comparison animation at this site: http://www.sorting-algorithms.com/

#### What is the time complexity of Shell sort?

Shell Sort is a comparison based sorting. Time complexity of Shell Sort depends on gap sequence . Its best case time complexity is O(n* logn) and worst case is O(n* log 2 n). Time complexity of Shell sort is generally assumed to be near to O(n) and less than O(n 2) as determining its time complexity is still an open problem.
