Difference Betwixt Comparing (Quicksort) In Addition To Non-Comparison (Counting Sort) Based Sorting Algorithms?
For many of you, this powerfulness last a surprise that how y'all tin form or adapt items without comparing alongside each other, precisely it's possible. There are some sorting algorithms that perform sorting without comparing the elements rather past times making for sure supposition nigh the information they are going to sort. The procedure is known equally non-comparison sorting together with algorithms are known equally the non-comparison based sorting algorithms. No comparing sorting includes Counting form which sorts using key value, Radix sort, which examines private bits of keys, together with Bucket Sort which examines bits of keys. These are likewise known equally Liner sorting algorithms because they form inward O(n) time. They brand for sure supposition nigh information therefore they don't involve to become through comparing conclusion tree.
So, based upon how they work, y'all tin broadly form the sorting algorithms into ii categories, comparing based e.g. QuickSort or MergeSort, together with non-comparison based e.g. Counting form or Radix Sort. As the refer suggest, the cardinal divergence betwixt a comparing based together with a non-comparison based sorting algorithm is the comparing decision.
In the showtime type, a comparator is required to compare numbers or items. Basically, this comparator defines the ordering e.g. numerical order, lexicographical order, likewise known equally lexicon lodge to adapt elements. On the other hand, non-comparison based sorting algorithms don't role comparing precisely rely on integer arithmetics on keys.
While, heap sort, quick sort, together with merge form takes O(NlogN) fourth dimension inward the best instance together with around O(n^2) inward the worst case. Can nosotros create ameliorate than O(NlogN) using sorting algorithm? tin nosotros form items inward O(n) fourth dimension using these sorting algorithms? Well, the respond is No.
It tin last proven that whatever comparison-based sorting algorithm volition accept at least O(NlogN) operations to form n elements, therefore y'all involve a non-comparison based sorting algorithm which allows y'all to form elements inward linear time.
The linear sorting algorithms are likewise 1 of the pop data construction together with algorithm questions inward recent times, so y'all ameliorate know nigh it.
Due to the working divergence betwixt these ii types of algorithms, generally, the non-comparison based sorting algorithms similar Radix Sort, Counting Sort, together with Bucket Sort are faster than QuickSort, Merge Sort together with Heap Sort. Let's catch a yoke of to a greater extent than differences betwixt these sorting algorithms to empathise better.
The latter type is likewise known equally Integer form because it relies on integer arithmetics for sorting rather than comparison.
Speed
One of the most critical differences betwixt these ii sorting algorithms is speed. Non-comparison sorting is normally faster than sorting because of non doing the comparison. The restrict of speed for comparison-based sorting algorithm is O(NlogN) piece for non-comparison based algorithms its O(n) i.e. linear time.
Comparator
Comparison based sorting algorithm e.g. QuickSort, Merge Sort. or Heap Sort requires a Comparator to form elements e.g. piece sorting an array of String, precisely non-comparison based sorting algorithms doesn't require whatever comparator.
Usage
Non-Comparison based sorting algorithm tin role to form whatever object provided it provides Comparator to define ordering, precisely a non-comparison based sorting algorithm tin non last used to form anything other than integers, that's why the are likewise known equally integer sorting. You tin likewise catch Introduction of Algorithms to acquire to a greater extent than nigh the O(n) sorting algorithms.
Examples
The QuickSort, Merge Sort, Heap Sort, Selection Sort, Bubble Sort together with Insertion Sort, piece some pop representative of non-comparison based sorting is Radix Sort, Counting Sort, Bucket Sort etc
Memory Complexity
The best instance for retentiveness complexity alongside the comparing based sorting is O(1) because it's possible to form an array of numbers inward house i.e. without using whatever additional memory. You tin catch the code for inward house Quicksort algorithm here. On the other hand, retentiveness complexity for non-comparison based sorting algorithm is ever O(n).
CPU complexity
The lower jump of CPU complexity or how much fourth dimension it accept for the algorithm to form due north numbers inward the worst instance is O(NlogN), precisely inward the instance of non-comparison based sorting the CPU complexity lower jump is O(n) i.e. the worst instance is fifty-fifty worse alongside non-comparison based sorting algorithms.
Here is a dainty animation of some of the pop comparison-based sorting algorithms:
That's all nigh the difference betwixt comparing together with non-comparison based sorting algorithms. Most of the mutual sorting algorithms autumn into the category of comparing based sorting algorithms e.g. quicksort, mergesort etc together with those are the to a greater extent than probable y'all volition role inward the existent world, precisely specialized non-comparison algorithms e.g. counting form together with bucket form tin last real useful if the laid upwardly of input run across the pre-conditions required. You tin farther read, Introduction to Algorithms past times Thomas H. Cormen to acquire to a greater extent than nigh non-comparison based sorting algorithms e.g. bucket sort.

If y'all similar this article so delight portion alongside your friends together with colleagues.

So, based upon how they work, y'all tin broadly form the sorting algorithms into ii categories, comparing based e.g. QuickSort or MergeSort, together with non-comparison based e.g. Counting form or Radix Sort. As the refer suggest, the cardinal divergence betwixt a comparing based together with a non-comparison based sorting algorithm is the comparing decision.

On the other hand, non-comparison based sorting algorithms don't role comparing precisely rely on integer arithmetics on keys.
Why Non-Comparison based Algorithms?
Some of y'all powerfulness last thinking why create nosotros involve non-comparison based algorithms at all, isn't comparing based sorting algorithms is enough? Well, if y'all await at the performance of comparing based sorting algorithm, y'all volition realize that Bubble sort, Selection Sort, together with Insertion sort takes around O(n^2) fourth dimension to form n items.While, heap sort, quick sort, together with merge form takes O(NlogN) fourth dimension inward the best instance together with around O(n^2) inward the worst case. Can nosotros create ameliorate than O(NlogN) using sorting algorithm? tin nosotros form items inward O(n) fourth dimension using these sorting algorithms? Well, the respond is No.
It tin last proven that whatever comparison-based sorting algorithm volition accept at least O(NlogN) operations to form n elements, therefore y'all involve a non-comparison based sorting algorithm which allows y'all to form elements inward linear time.
The linear sorting algorithms are likewise 1 of the pop data construction together with algorithm questions inward recent times, so y'all ameliorate know nigh it.
