Which is the best algorithm for sorting?


Which is the fastest sorting algorithm in Java?

Quicksort is a fast, recursive, non-stable sort algorithm which works by the divide and conquer principle. Quicksort will in the best case divide the array into almost two identical parts. It the array contains n elements then the first run will need O(n). Sorting the remaining two sub-arrays takes 2* O(n/2).

Which is faster insertion or 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 of the following is the biggest advantage of selection sort?

Which of the following is the biggest advantage of selection sort? Explanation: Selection sort works by obtaining least value element in each iteration and then swapping it with the current index. So it will take n swaps under any condition which will be useful when memory write operation is expensive.

What are the advantages and disadvantages of selection sort?

The primary disadvantage of the selection sort is its poor efficiency when dealing with a huge list of items….Advantages And disadvantages of sorting.

Advantages Disadvantages
It is able to deal well with a huge list of items. If the list is already sorted than bubble sort is much more efficient than quick sort

What are the advantages and disadvantages of quick sort?

On the average it runs very fast, even faster than Merge Sort. It requires no additional memory. when given a sorted array. It is not stable.

What’s the biggest advantage of the bubble sort?

The primary advantage of the bubble sort is that it is popular and easy to implement. Furthermore, in the bubble sort, elements are swapped in place without using additional temporary storage, so the space requirement is at a minimum.

What are the real time applications of quick sort?


  • Quicksort is used everywhere where a stable sort is not needed.
  • Variants of quicksort are used to separate the k smallest or largest elements.
  • Quicksort’s divide-and-conquer enables the use of parallelization.

What are the applications of sorting?

We have seen two important applications of sorting: (1) as an aid to searching, and (2) for matching entries in lists. Sorting is also used in the solution of many other more complex problems.

Which is the best sorting algorithm for large data?

While there are a large number of sorting algorithms, in practical implementations a few algorithms predominate. Insertion sort is widely used for small data sets, while for large data sets an asymptotically efficient sort is used, primarily heap sort, merge sort, or quicksort.

Which is the fastest sorting algorithm in C++?

fastest sorting algorithm will be the merge sort. since the time complexity is less even in the worst case(nlogn). Even if the array is properly arranged or not,it wouldn’t take more than nlogn steps to sort the array. C++ STL sort function is fastest.
