Which sorting is best and why?
Even though quick-sort has a worst case run time of Θ(n2), quicksort is considered the best sorting because it is VERY efficient on the average: its expected running time is Θ(nlogn) where the constants are VERY SMALL compared to other sorting algorithms..
Which is better insertion sort or bubble sort?
well bubble sort is better than insertion sort only when someone is looking for top k elements from a large list of number i.e. in bubble sort after k iterations you’ll get top k elements. However after k iterations in insertion sort, it only assures that those k elements are sorted.
Why is bubble sort slow?
Why is bubble sort so slow? Because it does an awful lot of comparisons and swaps – for N things to sort, a dumb implementation going to take (roughly) N*N or so. … For comparison, better sorting methods need N*log(N) (if you don’t understand logarithms, “number of digits in the number” is close enough).
What is difference between selection sort and bubble sort?
Bubble sort and Selection sort are the sorting algorithms which can be differentiated through the methods they use for sorting. Bubble sort essentially exchanges the elements whereas selection sort performs the sorting by selecting the element.
Which is the slowest sorting procedure?

Is insertion sort faster than selection sort?
Among both of the sorting algorithm, the insertion sort is fast, efficient, stable while selection sort only works efficiently when the small set of elements is involved or the list is partially previously sorted.
Which is the fastest sorting algorithm?
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.
Why is insertion sort better?
6 Answers. Insertion sort is faster for small n because Quick Sort has extra overhead from the recursive function calls. Insertion sort is also more stable than Quick sort and requires less memory.
How efficient is bubble sort?
Performance. Bubble sort has a worst-case and average complexity of О(n2), where n is the number of items being sorted. Most practical sorting algorithms have substantially better worst-case or average complexity, often O(n log n). … Therefore, bubble sort is not a practical sorting algorithm.
What sorting does Python use?
Timsort is a hybrid stable sorting algorithm, derived from merge sort and insertion sort, designed to perform well on many kinds of real-world data. It was implemented by Tim Peters in 2002 for use in the Python programming language. … Timsort has been Python’s standard sorting algorithm since version 2.3.
Is radix sort faster than Quicksort?
6 Answers. Unlike radix sort, quicksort is universal, while radix sort is only useful for fix length integer keys. Thus in real life scenario quicksort will be very often faster than radix sort.
Why would you choose insertion sort over bubble sort?
The reasoning would be that bubble sort always swaps two items at a time which is trivial on both, array and linked list (more efficient on arrays), while insertion sort inserts at a place in a given list which is trivial for linked lists but involves moving all subsequent elements in an array to the right.
What is the best time complexity of bubble sort?
The main advantage of Bubble Sort is the simplicity of the 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.
Is bubble sort ever useful?
Bubble sort is easy to implement and it is fast enough when you have small data sets. … Since this algorithm is easy to implement it is easy to support, and it is important in real application life cycle to reduce effort for support.
