This article will explain in detail how to achieve insertion sorting in web development. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Insert sort

Although the code implementation of inserting sorting is not as simple and crude as bubbling sorting and selective sorting, its principle should be the easiest to understand, because anyone who has played cards should be able to understand it in a second. Insertion sorting is the simplest and most intuitive sorting algorithm. Its working principle is to scan the unsorted data from back to front in the sorted sequence to find the corresponding position and insert it.

Algorithm step

The first to be sorted sequence the first element as an ordered sequence, the second element to the last element as an unsorted sequence.

The unsorted sequence is scanned from beginning to end, and each element scanned is inserted into the appropriate position of the ordered sequence. (if the element to be inserted is equal to an element in the ordered sequence, the element to be inserted is inserted after the equivalent element. ).

Algorithm demonstration

Process interpretation of sorting animation

At the beginning, the number on the left has been sorted, and the number 5 does not move.

Then, take out the remaining unoperated left number 3

Compare it with the number on the left that has been manipulated

If the number on the left is larger, swap the two numbers

In this case, because 5 is greater than 3, two numbers are exchanged.

Repeat until a smaller number or number reaches the left end.

The number 3 has been sorted.

Next, take out the remaining unoperated left number 4 as before.

Compare with the adjacent number on the left

In this case, because 5 is greater than 4, two numbers are exchanged.

Continue to operate, because 3 is less than 4, that is, a smaller number appears, so 4 stops moving

The number 4 has been sorted.

Repeat the same operation until all the numbers are sorted

Code implementation

In order to better let readers use their familiar programming language to understand animation, the author will post the reference code of a variety of programming languages, all from the Internet.

C++ code implementation

Java code implementation

Python code implementation

JavaScript code implementation
