How to implement a sorting algorithm in C language
This article is about how to implement a sorting algorithm in C language. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it with the editor.
Bubbling sort
Bubble sorting (English: BubbleSort) is a simple sorting algorithm. It repeatedly visits the sequence to be sorted, compares two elements at a time, and swaps them if they are in the wrong order (such as big to small, initials A to Z).
Select sort
Selective sorting (Selectionsort) is a simple and intuitive sorting algorithm. How it works is as follows. First find the smallest (large) element in the unsorted sequence and store it at the beginning of the sorted sequence, then continue to find the smallest (large) element from the remaining unsorted elements, and then put it at the end of the sorted sequence. And so on until all the elements are sorted.
Insert sort
Insertion sorting (English: InsertionSort) is a simple and intuitive sorting algorithm. It works by building an ordered sequence, scanning the unsorted data from back to front in the sorted sequence, finding the corresponding position and inserting it. Insertion sorting is usually implemented by in-place sorting (that is, only the extra space of {\ displaystyleO (1)} {\ displaystyleO (1)} is needed), so in the process of scanning from back to forward, the sorted elements need to be moved backward step by step to provide insertion space for the latest elements.
Hill ranking
Hill sorting, also known as decreasing incremental sorting algorithm, is a more efficient and improved version of insert sorting. Hill sorting is an unstable sorting algorithm.
Hill sorting is an improved method based on the following two properties of insertion sorting:
Insertion sorting is efficient when operating on almost sorted data, that is, it can achieve the efficiency of linear sorting.
But insert sorting is generally inefficient because it can only move data one bit at a time.
The above is how to implement a sorting algorithm in C language. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
