## Which is best algorithm for sorting?

QuicksortThe time complexity of Quicksort is O(n log n) in the best case, O(n log n) in the average case, and O(n^2) in the worst case. But because it has the best performance in the average case for most inputs, Quicksort is generally considered the “fastest” sorting algorithm.

## Which sorting algorithm is used by Google?

PageRankCurrently, PageRank is not the only algorithm used by Google to order search results, but it is the first algorithm that was used by the company, and it is the best known.

## Which is the easiest sorting algorithm?

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.

## Why is bubble sort N 2?

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).

## How many types of Google algorithms are there?

fiveGoogle has issued five major algorithm updates, named (in chronological order) Panda, Penguin, Hummingbird, Pigeon, and Fred.

## Is PageRank still used?

Yes, PageRank is still used in our algorithms, among a number of other signals,” a Google Spokesperson confirmed. … A few weeks ago Google updated the PageRank patent after they’ve shut down the toolbar, to stop people from focusing on the numbers.

## Which sorting algorithm is used in STL?

In more details it is implemented using hybrid of QuickSort, HeapSort and InsertionSort.By default, it uses QuickSort but if QuickSort is doing unfair partitioning and taking more than N*logN time, it switches to HeapSort and when the array size becomes really small, it switches to InsertionSort.

## What is the slowest sorting algorithm?

HeapSort: It is the slowest of the sorting algorithms but unlike merge and quick sort it does not require massive recursion or multiple arrays to work. Merge Sort: The merge sort is slightly faster than the heap sort for larger sets, but it requires twice the memory of the heap sort because of the second array.

## What is bubble sort algorithm?

Bubble sort, sometimes referred to as sinking sort, is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order. … The algorithm, which is a comparison sort, is named for the way smaller or larger elements “bubble” to the top of the list.

## How many types of sorting algorithms are there?

twoThere are two broad types of sorting algorithms: integer sorts and comparison sorts. Comparison sorts compare elements at each step of the algorithm to determine if one element should be to the left or right of another element.
