Foreword In the field of software development, it is crucial to understand and master multiple sorting algorithms. Sorting is not only a fundamental step in solving many computational problems, but in practical applications, choosing an appropriate sorting algorithm can significantly improve the performance of a program. This article will delve into techniques for sorting different […]

Golang standard library: sort package – sorting algorithm
3.1 sort – sorting algorithm This package implements four basic sorting algorithms: insertion sort, merge sort, heap sort, and quick sort. But these four sorting methods are not public, they are only used internally by the sort package. Therefore, when sorting a data set, you do not need to consider which sorting method should be […]
Three basic algorithms for sorting with time complexity n^2
Foreword: Bubble sort, selection sort, and insertion sort are all sorting algorithms with a time complexity of n^2. They are also the basis for us to learn other sorting algorithms later. Next, I will explain these three sorting algorithms to you in as much detail as possible. Time and optimization plan, if you have gained […]
TexGen simple model corresponding to inp file simple sorting-2
Model The default is the simplest woven composite material. When editing the material properties, it is found that the matrix properties are set normally and it is an isotropic material, but the material properties of the yarn do not have elastic properties settings. After exporting the inp file and importing it into ABAQUS, you can […]

list.stream().sorted() Java8 Stream’s sorted() sorting. Forward order, reverse order, multi-field sorting
For collection sorting, java8 can use sorted() of the Stream stream for sorting. ExampleBeans We will use this Bean as an example below. public class Order {<!– –> private String weight; private Double price; private String dateStr; //Ignore getter, setter, constructor, toString } Field sorting The first is the comparator Comparator, which has the following […]
