Which of the sorting algorithms has the best Big O rating?

When looking at many of the most commonly used sorting algorithms, the rating of O(n log n) in general is the best that can be achieved. Algorithms that run at this rating include Quick Sort, Heap Sort, and Merge Sort. Quick Sort is the standard and is used as the default in almost all software languages.

What does Big O complexity have to do with sorting algorithms?

Big-O, along with Big-Omega and Big-Theta, describe the performance of an algorithm by estimating the number of operations required as the size of the input approaches infinity.

What is the best suited Big O notation for typical sorting algorithms good Behaviour?

For typical sorting algorithms, a good behavior is O(n log n) and a bad behavior is O(n2). Computational complexity of swaps (for “in place” algorithms).

Which sorting algorithm has the fastest best case performance in terms of Big O?)?

Merge sort is more efficient and works faster than quick sort in case of larger array size or datasets. Quick sort is more efficient and works faster than merge sort in case of smaller array size or datasets.

Which algorithm gives better performance in 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 sort algorithm is best?
