有没有实现这样功能的相关数组函数？该如何处理
有没有实现这样功能的相关数组函数？
$a0 =array(9,7,8,6,5,8,3,5,11,5);
就是数组里的值都减去一个当前数组值小于的数的函数？

How does springboot read lists, arrays, map collections and objects in yml files?
May 11, 2023 am 10:46 AM
application.yml defines the list collection. The first way is to use the @ConfigurationProperties annotation to obtain all the values of the list collection type:code:status:-200-300-400-500. Write the entity class corresponding to the configuration file. What needs to be noted here is that defining the list Collection, first define a configuration class Bean, and then use the annotation @ConfigurationProperties annotation to obtain the list collection value. Here we will explain the role of the relevant annotations. @Component hands over the entity class to Spring management @ConfigurationPropertie
How to set expiration time map in Java
May 04, 2023 am 10:13 AM
1. Technical background In actual project development, we often use caching middleware (such as redis, MemCache, etc.) to help us improve the availability and robustness of the system. But in many cases, if the project is relatively simple, there is no need to specifically introduce middleware such as Redis to increase the complexity of the system in order to use caching. So does Java itself have any useful lightweight caching components? The answer is of course yes, and there is more than one way. Common solutions include: ExpiringMap, LoadingCache and HashMap-based packaging. 2. Technical effects to realize common functions of cache, such as outdated deletion strategy, hotspot data warm-up 3. ExpiringMap3.
How to convert objects to Maps in Java - using BeanMap
May 08, 2023 pm 03:49 PM
There are many ways to convert javabeans and maps, such as: 1. Convert beans to json through ObjectMapper, and then convert json to map. However, this method is complicated and inefficient. After testing, 10,000 beans were converted in a loop. , it takes 12 seconds! ! ! Not recommended. 2. Obtain the attributes and values of the bean class through Java reflection, and then convert them into the key-value pairs corresponding to the map. This method is the second best, but it is a little more troublesome. 3. Through net.sf.cglib.beans.BeanMap Method in the class, this method is extremely efficient. The difference between it and the second method is that because of the use of cache, the bean needs to be initialized when it is first created.
What are the ways to implement thread safety for Map in Java?
Apr 19, 2023 pm 07:52 PM
Method 1. Use HashtableMapashtable=newHashtable(); This is the first thing everyone thinks of, so why is it thread-safe? Then take a look at its source code. We can see that our commonly used methods such as put, get, and containsKey are all synchronous, so it is thread-safe publicsynchronizedbooleancontainsKey(Objectkey){Entrytab[]=table;inthash=key.hashCode( );intindex=(hash&0x7FFFFFFF)%tab.leng
Optimize the performance of Go language map
Mar 23, 2024 pm 12:06 PM
Optimizing the performance of Go language map In Go language, map is a very commonly used data structure, used to store a collection of key-value pairs. However, map performance may suffer when processing large amounts of data. In order to improve the performance of map, we can take some optimization measures to reduce the time complexity of map operations, thereby improving the execution efficiency of the program. 1. Pre-allocate map capacity. When creating a map, we can reduce the number of map expansions and improve program performance by pre-allocating capacity. Generally, we
How to configure and use the map module in Nginx server
May 21, 2023 pm 05:14 PM
The map directive uses the ngx_http_map_module module. By default, nginx loads this module unless artificially --without-http_map_module. The ngx_http_map_module module can create variables whose values are associated with the values of other variables. Allows classification or simultaneous mapping of multiple values to multiple different values and storage in a variable. The map directive is used to create a variable, but only performs the view mapping operation when the variable is accepted. For processing requests that do not reference variables, this The module has no performance shortcomings. 1.ngx_http_map_module module instruction description map syntax
Sort array using Array.Sort function in C#
Nov 18, 2023 am 10:37 AM
Title: Example of using the Array.Sort function to sort an array in C# Text: In C#, array is a commonly used data structure, and it is often necessary to sort the array. C# provides the Array class, which has the Sort method to conveniently sort arrays. This article will demonstrate how to use the Array.Sort function in C# to sort an array and provide specific code examples. First, we need to understand the basic usage of the Array.Sort function.

Things to note when Golang functions receive map parameters
Jun 04, 2024 am 10:31 AM
When passing a map to a function in Go, a copy will be created by default, and modifications to the copy will not affect the original map. If you need to modify the original map, you can pass it through a pointer. Empty maps need to be handled with care, because they are technically nil pointers, and passing an empty map to a function that expects a non-empty map will cause an error.
