What is the best sorting algorithm for large data?
For large number of data sets, Insertion sort is the fastest. In the practical sorting, this case occurs rarely. Note that randomized Quicksort makes worst cases less possible, which will be the case for in-order data if the pivot point in Quicksort is chosen as the first element.
What is the most efficient way to sort a million integers?
8 Answers. You can use counting sort. Counting sort (sometimes referred to as ultra sort or math sort) is a sorting algorithm which (like bucket sort) takes advantage of knowing the range of the numbers in the array to be sorted (array A).
How do I sort large amounts of data?
- For sorting a very large file , we can use external sorting technique.External sorting is an algorithm that can handle massive amounts of data.
- using external merge sort.
- For sorting a very large file , we can use external sorting technique.External sorting is an algorithm that can handle massive amounts of data.
Which is the best sorting algorithm in Java?

Insertion Sort | O (n) |
Selection Sort | O(n^2) |
What is the best algorithm for sorting data?
There’s no one algorithm that’s clearly the “best” algorithm. If there were, we’d be using it everywhere! Instead, it depends on a bunch of factors. For starters, can you fit your data into main memory? If you can’t, then you’d need to rely on an external sorting algorithm.
Why can’t we choose heap sort as the best sorting algorithm?
If swapping of the two elements has negligible time cost, then why can’t we choose heap sort as the best sorting algorithm in this case because it is in place as well as O (n log n)?. In case of Merge sort it requires another O (n) space; if the data is very large then we can’t use this algorithm.
Is quick sort the fastest way to sort data?
Quick sort is fastest, but it is not always O (N*log N), as there are worst cases where it becomes O (N2). Quicksort is probably more effective for datasets that fit in memory. For larger data sets it proves to be inefficient so algorithms like merge sort are preferred in that case.
When memory space is limited what is the simplest sorting algorithm?
When memory space is limited because it makes the minimum possible number of swaps during sorting. This sorting algorithm is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in the wrong order.
