How to implement selective sorting in web Development

This article mainly shows you "how to achieve selection sorting in web development", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "how to achieve selection sorting in web development" this article.

Select sort

Selective sorting is a simple and intuitive sorting algorithm, no matter what data is entered, it is O (n ²) time complexity. So when using it, the smaller the data, the better. The only benefit may be that it doesn't take up extra memory space.

Algorithm step

First, find the smallest (largest) element in the unsorted sequence and store it at the beginning of the sorted sequence.

Continue to look for the smallest (largest) element from the remaining unsorted elements, and then put it at the end of the sorted sequence.

Repeat the second step until all the elements are sorted.

Algorithm demonstration

Process interpretation of sorting animation

Linearly search the sequence and find the minimum value, which is 2

Replace the minimum value with the number at the left end of the sequence, that is, swap 2 and 4

At this time 2 has been sorted.

Continue to linearly search the remaining series to find the minimum value, and then find 3.

Replace the minimum value with the number at the left end of the sequence, that is, swap 3 and 4

At this time, 2 and 3 are sorted.

Continue to linearly search the remaining series to find the minimum value, and then find 4.

If the minimum is already on the left, no action is performed, so no processing is done at this time

At this time, 2, 3 and 4 have been sorted.

Repeat the same operation until all the numbers are sorted

Code implementation
