您的老板要求您编写一个“ hello world”程序。由于您获得了代码行的报酬，因此您希望使其尽可能复杂。但是，如果您仅添加无用的代码行，或者显然是无用的或令人困惑的内容，那么您将永远无法通过代码审查获得它。因此，挑战在于：

编写一个“ hello world”程序，该程序在您可以为代码中的每种复杂性给出“合理性”的条件下尽可能复杂。

该程序所需的行为是仅输出一行“ Hello world”（不带引号，但末尾带有换行符），然后成功退出。

“辩解”包括：

• 流行语兼容性（“现代软件是面向对象的！”）
• 公认的良好编程习惯（“每个人都知道您应该分开模型和视图”）
• 可维护性（“如果这样做，我们以后可以更轻松地进行XXX”）
• 当然还有其他可以证明的理由（在其他情况下）使用真实代码。

显然，愚蠢的理由将不被接受。

另外，您还必须“证明”您选择的语言（因此，如果您选择固有的冗长语言，则必须说明为什么它是“正确”的选择）。有趣的语言，如unlambda相似或INTERCAL是不能接受的（除非你可以给一个非常使用它们很好的理由）。

符合条件的条目的分数计算如下：

• 每条陈述1分（或您选择的语言所对应的任何陈述）。
• 对于函数，类型，变量等的每个定义，需要加1分（主函数除外，如适用）。
• 每个模块的use语句，文件include指令，命名空间using语句或类似名称为1点。
• 每个源文件1分。
• 每个必要的前向声明要加1分（如果您可以通过重新排列代码来摆脱它，则必须“证明”选择的排列为什么是“正确”的）。
• 每个控制结构1点（如果，同时，用于等）

请记住，您必须“调整”每一行。

如果所选语言足够不同，以致无法应用此方案（并且您可以为其使用提供很好的“证明”），请提出一种与您选择的语言最相似的评分方法。

要求参赛者计算其参赛分数并将其写在答案中。

C ++，trollpost

您可以证明最复杂的“ Hello world”程序

#include <iostream>

using namespace std;

int main(int argc, char * argv[])
{
    cout << "Hello, world!" << endl;
    return 0;
}

我的大脑不能证明写更长的书:)

在这里，我将通过上述脚本语言的操作符以及数据结构（如列表和字典）的生成器，以优美有效的方式解决称为Python的脚本语言的强大功能和可用性。

但是，恐怕我不完全理解“尽可能复杂”和“合理化”这两个词的使用。不过，这是我惯用的，不言自明的，直接的策略的摘要，紧接着是您将发现的Python实际实现，完全符合该语言的俏皮，高级特性：

1. 定义字母–显而易见的第一步。为了扩展性，我们选择整个ascii范围。请注意，使用内置列表生成器可以为我们节省数小时的繁琐列表初始化。

2. 告诉我们字母表中每个字母要使用多少个。这只是表示为另一个列表！

3. 将这两个列表合并到一个方便的字典中，其中的键是ascii点，值是所需的数量。

4. 我们现在准备开始制作角色！首先从字典中创建一个字符串。这将包含我们最终输出中所需的所有字符，以及每个字符的正确数量！

5. 声明所需的字符顺序，并启动一个新列表，该列表将保留我们的最终输出。通过简单的迭代，我们将生成的字符放到最终位置并打印结果！

这是实际的实现

# 1: Define alphabet:
a = range(255)

# 2: Letter count:
n = (0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,

# 3: Merge to dictionary:
d = { x: y for x, y in zip(a,n) }

# 4: 'Initialize' characters
l = ''.join([chr(c) *n for c,n in d.items()])

# 5: Define the order of the characters, initialize final string
#    and sort before outputting:
z = [6,5,0,7,11,1,2,3,4,8,9]
o = [0] * 13

for c in l:
    i = z.pop(0)
    o[i] = c

print ''.join(o)

_{好的，只是做了一个简短但愚蠢的问题，并添加了一堆文本而不是TL; DR代码解决方案}

好吧，我把帽子扔进了戒指。

ContentProvider.scala：

/*  
    As we all know, the future is functional programming. 

    And one of the mantras of pure functional programming is, to avoid mutable data 
    as hell. Using case classes and case objects allows us to create very small,
    immutable Flight-Weight-Pattern like objects (Singletons, if you like).

    I'm choosing scala, because its compiled to bytecode for the JVM and therefore very 
    portable. I could of course have implemented it in Java, but as we all know,
    Javacode is boilerplaty, while scala is a concise language.     

    S: for easy grepping of scoring hints.

当然，对于纯函数方法，0个臭味变量。一切都布置在类型系统中，并且很简单。聪明的编译器可以对其进行最优化。

该程序清晰，简单且易于理解。它易于测试且通用，并且避免了过度设计的陷阱（我的团队想将indexedOHWCChain和indexedLHWCChain重新编码为一个通用的次要特征，该特征具有目标数组和长度字段，但这简直太愚蠢了！）。

纯Bash 没有叉子 （一些计数，似乎是85左右...）

• 6个函数initRotString 2个变量，3个语句
• 14个功能binToChar 2个变量，7个语句+子定义：1个func，1个var，2个stat
• 34个函数rotIO 9个变量，25个语句
• 9个函数RLE 4个变量，5个statments
• 22个 主要 13个变量，9个陈述

特点：

• 二级RLE：第一个二进制编码每个字符，第二个用于重复字符
• 基于键的修改后的rot13：rotIO函数像Rot13一样执行旋转，但是对96个值而不是26个值（* rot47）进行旋转，但是通过提交的键进行了移位。
• 第二版使用gzip和uuencode通过perl（比的安装更为普遍uudecode）

众所周知，摩尔定律已经有了新的发展，未来十年计算能力的所有真正进步都将出现在GPU中。考虑到这一点，我使用LWJGL编写了一个速度非常快的Hello World程序，该程序充分利用了GPU的优势来生成字符串“ Hello World”。

由于我正在编写Java，因此从复制和粘贴别人的代码开始是惯用的，因此我使用了http://lwjgl.org/wiki/index.php?title=Sum_Example

组装（x86，Linux / Elf32）：55分

每个人都知道，当您需要快速的程序时，需要使用汇编语言编写。

有时我们不能依靠ld自己的工作来完成-为了获得最佳性能，最好为hello world可执行文件构建自己的Elf标头。该代码仅需nasm构建，因此非常可移植。它不依赖外部库或运行时。

每行和每条语句对于程序的正确运行都是至关重要的-没有多余的东西，什么都不能省略。

而且，这确实是不使用链接器的最短方法-没有不必要的循环或声明来掩盖答案。

PHP / HTML / CSS（88分）

所有代码都在这里提供：https : //github.com/martin-damien/code-golf_hello-world

• 该“ Hello World”使用PHP的Twig模板语言（http://twig.sensiolabs.org/）。
• 我使用自动加载机制来简单地动态加载类。
• 我使用Page类，它可以处理多种类型的元素（实现XMLElement接口），并以正确的XML格式重新设置所有这些元素。
• 最后，我使用闪亮的CSS来显示漂亮的“ Hello World” :)

来自K＆R的输出C编程语言示例：

hello, world!

Ti-Basic 84，1点

:Disp "HELLO WORLD!"

Ti-Basic非常基础。但是，如果您真的想要一个合理的解释，这里是：

: 启动每个命令，函数，语句，结构，子程序，将其命名

Disp 是预定义的功能，可在屏幕上显示参数

aka whitespace让函数Disp知道它已经被调用，并且参数应该跟随空格的单个字符，该空格实际上与Disp

" 开始定义字符串文字

HELLO WORLD 字符串文字中的部分文本

! 尽管它是阶乘数学运算符，但由于它位于字符串文字中，因此不会进行评估

" 结束字符串文字的定义

所以，我有一个非常……特殊的经理。他有一个奇怪的想法，即程序越简单，越漂亮，它应该越具有艺术性。由于Hello World可以说是最容易编写的程序之一，因此他要求的东西太棒了，可以挂在墙上。经过研究后，他坚持要用Piet编写。

现在，我不是一个质疑最聪明的人能胜任高层管理人员的优点的人，所以我受命“编写”该程序，该程序可以在此在线piet解释器上运行。也许是时候寻找一个更健全的经理了……

C中的唇形图：

int main(){
    printf("H%cllo World\n", 'd'+1);
}

我的计算机上的btwn'w'和'r'是bronn。它与som languags产生因果关系。C中几乎所有的PR编译器指令都是这样的。从头开始，cod发出有关printf（）隐式声明的警告，因为我无法使用#includ（stdio.h），但它运行良好。

作为社区Wiki，我将其作为参考。这是C＃的一种不好的做法。我定义了自己的ascii数据结构。我不希望这成为竞争对手，而是“孩子，你看到那边的那个人……如果你不吃蔬菜，你会变得像他一样”。

如果您容易受到错误代码的干扰，请立即查找

我通常用它在万圣节吓到孩子们。您还应该注意，我不能将我所有的256个ASCII字符都放在这里，因为总字符数增加到40,000。请勿出于以下两个原因尝试重现此内容：

• 这比高尔夫代码更可怕，更可怕，更糟糕。

积分：183

• 62条声明*
• 10个类+ 25个方法（属性的getter和setter是不同的）+ 8个变量声明（我认为）= 43个声明
• 没有模块使用语句。但是，它确实有一些默认值，使用完整资格是我打保龄球的一部分。那么也许1 System呢？好吧，无论如何，假设0。
• 1个源文件。
• 不是使用前向声明的语言。好吧，1 MustOverride，我将数。
• 76条控制声明。没有手动计数，因此可能会有些不准确。

总计：62 + 43 + 0 + 1 + 1 + 76 = 183

文献资料

• 代码中没有注释。这有助于减少混乱情况，并且不需要注释，因为我是唯一的开发人员，而我们拥有如此惊人的详细文档-再次由您真正撰写。
• 在OptimizedStringFactory拥有优化的字符串。它具有一个高速缓存，该高速缓存允许使用对有效IEnumerable(Of Char)s的引用，同时避免引用的内在问题。引起我注意的是.NET包含某种字符串池。但是，内置缓存对我们正在使用的对象了解不多-不可靠，因此我创建了自己的解决方案。
• 在ConcurrentOutputCharacter类允许多线程的，单字符输出的容易同步。这可以防止输出乱码。在面向对象编程的最佳实践中，对它进行了声明，MustInherit并从中派生出每个要输出的字符或字符串，并进行了声明NotInheritable。它包含几个断言，以确保传递有效数据。
• *Character对于我们的特定字符串输出情况，每个字符都包含一个字符。
• 主模块包含用于创建线程的代码。线程是一项非常新的功能，它使我们能够利用多核处理器并更有效地处理输出。为了防止代码重复，我使用了一个循环来创建字符。

美丽，不？

由于上述循环和继承，加上基于反射的动态类加载，它甚至可以扩展。这也可以防止过度混淆，因此没有人可以通过混淆来声明我们的代码。要更改字符串，只需创建一个字典，即可在反射代码动态加载它们之前将输入字符映射到不同的输出字符类。

Javascript，很多要点

• 完全集成的i18n支持
• 多平台JS，可以在具有可自定义上下文的Node和Web浏览器上运行（浏览器应使用“窗口”）
• 可配置的数据源，默认情况下使用静态“ Hello world”消息（以提高性能）
• 完全异步，并发性好
• 良好的调试模式，对代码调用进行时间分析。

说明

这将创建一个ASCII值及其相关字符的字典，因为它将允许代码仅使用这些值，而不能使用其他值。我们确保在单独的列表中引用元音，然后知道倒数第二个字符在两个字符串中重复出现。

完成此操作后，我们将创建一个词典列表，其中包含设置规则，这些规则定义了单词长度，单词的第一个，最后一个和重复字符，然后还设置了一个true / false语句来确定是否应检查重复。

完成此操作后，脚本将遍历字典列表，并通过一个函数创建该函数，该函数会创建参考字典中所有可能的字符排列，并在必要时小心添加任何重复的字符。

然后，它通过第二个函数输入，该函数为每个排列创建更多排列，但设置最大长度。这样做是为了确保我们找到想要咀嚼的单词。然后，在此过程中，它将通过使用if-else语句组合（确定是否值得吐出）的函数将其馈入。如果排列与语句所要求的相匹配，则它将发出true / false语句，并且调用它的函数会将其添加到列表中。

完成此操作后，脚本将从每个列表中获取第一项并将其组合以声明“ hello world”。

我还添加了一些调试功能，以使您知道它的运行速度。我选择这样做是因为如果您知道如何构造句子，则无需编写“ hello world”即可吐出“ hello world”。

好吧，这很好。

说明

i`I

询问用户是否要退出

@I:1_A#0_A

记录他们的答案

@I:0_A#:End

如果他们确实希望结束，则终止

t`Hello World"

如果他们没有结束，它将打印Hello World。

哈希然后用蛮力对“ Hello，World！”字符进行哈希处理，将这些字符添加到中StringBuilder，并使用Logger记录该字符。

                    try
                    {
                        sb.append(c);
                        break checking;
                    }
                    catch (Throwable t)
                    {
                        try
                        {
                            LOGGER.logrb(Level.SEVERE, ComplexHelloWorld.class.getName(), "main", null, "An unexpected error occurred", t);
                        }
                        catch (Throwable t2)
                        {
                            //welp.
                        }
                    }
        try
        {
            LOGGER.logrb(Level.INFO, ComplexHelloWorld.class.getName(), "main", null, sb + "", new Object[]
            {
            });
        }
        catch (Throwable t)
        {
            try
            {
                LOGGER.logrb(Level.SEVERE, ComplexHelloWorld.class.getName(), "main", null, "An unexpected error occurred", t);
            }
            catch (Throwable t2)

C＃-158

我告诉你，如今的开发人员，没有注意SOLID原则。如今，人们忽略了正确完成甚至简单任务的重要性。

首先，我们需要从需求开始：

• 将指定的字符串输出到控制台
• 允许本地化
• 遵循SOLID原则

首先，让我们从本地化开始。为了正确地对字符串进行本地化，我们需要在程序中使用该字符串的别名以及要在其中使用该字符串的语言环境。显然，我们需要以易于互操作的格式XML来存储此数据。为了正确执行XML，我们需要一个模式。

StringDictionary.xsd

<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="StringDictionary"
targetNamespace="http://stackoverflow.com/StringDictionary.xsd"
elementFormDefault="qualified"
xmlns="http://stackoverflow.com/StringDictionary.xsd"
xmlns:mstns="http://stackoverflow.com/StringDictionary.xsd"
xmlns:xs="http://www.w3.org/2001/XMLSchema">

<xs:element name="stringDictionary" type="localizedStringDictionary"/>

<xs:complexType name="localizedStringDictionary">
    <xs:sequence minOccurs="1" maxOccurs="unbounded">
        <xs:element name="localized" type="namedStringElement"></xs:element>
    </xs:sequence>
</xs:complexType>

<xs:complexType name="localizedStringElement">
    <xs:simpleContent>
        <xs:extension base="xs:string">
            <xs:attribute name="locale" type="xs:string"/>
        </xs:extension>
    </xs:simpleContent>
</xs:complexType>

<xs:complexType name="namedStringElement">
    <xs:sequence minOccurs="1" maxOccurs="unbounded">
        <xs:element name="translated" type="localizedStringElement"></xs:element>
    </xs:sequence>
    <xs:attribute name="name" type="xs:string"></xs:attribute>
</xs:complexType>

这定义了我们的XML结构，并使我们有了一个良好的开端。接下来，我们需要包含字符串的XML文件本身。将此文件作为项目中的嵌入式资源。

<?xml version="1.0" encoding="utf-8" ?>
<stringDictionary xmlns="http://stackoverflow.com/StringDictionary.xsd">
    <localized name="helloWorld">
        <translated locale="en-US">Hello, World</translated>
        <translated locale="ja-JP">こんにちは世界</translated>
    </localized>
</stringDictionary>

这样一来，我们绝对不想要的一件事就是程序中的任何硬编码字符串。使用Visual Studio在您的项目中创建将用于字符串的资源。确保更改XmlDictionaryName以匹配先前定义的XML字符串文件的名称。

由于我们是依赖关系反转，因此我们需要一个依赖关系容器来处理注册和创建对象。

IDependencyRegister.cs

public interface IDependencyRegister
{
    void Register<T1, T2>();
}

IDependencyResolver.cs

public interface IDependencyResolver
{
    T Get<T>();
    object Get(Type type);
}

我们可以在一个类中同时提供这两个接口的简单实现。

DependencyProvider.cs

public class DependencyProvider : IDependencyRegister, IDependencyResolver
{
    private IReadOnlyDictionary<Type, Func<object>> _typeRegistration;

    public DependencyProvider()
    {
        _typeRegistration = new Dictionary<Type, Func<object>>();
    }

    public void Register<T1, T2>()
    {
        var newDict = new Dictionary<Type, Func<object>>((IDictionary<Type, Func<object>>)_typeRegistration) { [typeof(T1)] = () => Get(typeof(T2)) };
        _typeRegistration = newDict;
    }

    public object Get(Type type)
    {
        Func<object> creator;
        if (_typeRegistration.TryGetValue(type, out creator)) return creator();
        else if (!type.IsAbstract) return this.CreateInstance(type);
        else throw new InvalidOperationException("No registration for " + type);
    }

    public T Get<T>()
    {
        return (T)Get(typeof(T));
    }

    private object CreateInstance(Type implementationType)
    {
        var ctor = implementationType.GetConstructors().Single();
        var parameterTypes = ctor.GetParameters().Select(p => p.ParameterType);
        var dependencies = parameterTypes.Select(Get).ToArray();
        return Activator.CreateInstance(implementationType, dependencies);
    }
}

从最低级别开始并逐步进行，我们需要一种读取XML的方法。在SOLID S和之后I，我们定义XML字符串字典代码使用的接口：

public interface IStringDictionaryStore
{
    string GetLocalizedString(string name, string locale);
}

考虑适当的性能设计。检索这些字符串将成为我们程序中的关键路径。并且，我们要确保始终检索正确的字符串。为此，我们将使用一个字典，它们的键是字符串名称和语言环境的哈希，并且值包含我们翻译的字符串。再一次，遵循单一责任原则，我们的字符串字典不应该在乎如何对字符串进行哈希处理，因此我们创建了一个接口并提供了基本的实现

IStringHasher.cs

public interface IStringHasher
{
    string HashString(string name, string locale);
}

Sha512StringHasher.cs

public class Sha512StringHasher : IStringHasher
{
    private readonly SHA512Managed _sha;
    public Sha512StringHasher()
    {
        _sha = new SHA512Managed();
    }
    public string HashString(string name, string locale)
    {
        return Convert.ToBase64String(_sha.ComputeHash(Encoding.UTF8.GetBytes(name + locale)));
    }
}

这样，我们可以定义XML字符串存储，该存储从嵌入式资源中读取XML文件，并创建一个包含字符串定义的字典。

EmbeddedXmlStringStore.cs

public class EmbeddedXmlStringStore : IStringDictionaryStore
{
    private readonly XNamespace _ns = (string)Resources.XmlNamespaceName;

    private readonly IStringHasher _hasher;
    private readonly IReadOnlyDictionary<string, StringInfo> _stringStore;
    public EmbeddedXmlStringStore(IStringHasher hasher)
    {
        _hasher = hasher;
        var resourceName = this.GetType().Namespace + Resources.NamespaceSeperator + Resources.XmlDictionaryName;
        using (var s = Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName))
        {
            var doc = XElement.Load(s);

            _stringStore = LoadStringInfo(doc).ToDictionary(k => _hasher.HashString(k.Name, k.Locale), v => v);
        }
    }

    private IEnumerable<StringInfo> LoadStringInfo(XElement doc)
    {
        foreach (var e in doc.Elements(_ns + Resources.LocalizedElementName))
        {
            var name = (string)e.Attribute(Resources.LocalizedElementNameAttribute);
            foreach (var e2 in e.Elements(_ns + Resources.TranslatedElementName))
            {
                var locale = (string)e2.Attribute(Resources.TranslatedElementLocaleName);
                var localized = (string)e2;
                yield return new StringInfo(name,locale,localized);
            }
        }
    }

    public string GetLocalizedString(string name, string locale)
    {
        return _stringStore[_hasher.HashString(name, locale)].Localized;
    }
}

和关联的StringInfo结构来保存字符串信息：

StringInfo.cs

public struct StringInfo
{
    public StringInfo(string name, string locale, string localized)
    {
        Name = name;
        Locale = locale;
        Localized = localized;
    }

    public string Name { get; }
    public string Locale { get; }
    public string Localized { get; }
}

由于我们可能有几种查找字符串的方法，因此我们需要将程序的其余部分与精确检索字符串的方式隔离开来，为此，我们定义IStringProvider，它将在程序的其余部分中用于解析字符串：

ILocaleStringProvider.cs

public interface ILocaleStringProvider
{
    string GetString(string stringName, string locale);
}

使用实现：

StringDictionaryStoreLocaleStringProvider.cs

public class StringDictionaryStoreLocaleStringProvider: ILocaleStringProvider
{
    private readonly IStringDictionaryStore _dictionaryStore;

    public StringDictionaryStoreStringProvider(IStringDictionaryStore dictionaryStore)
    {
        _dictionaryStore = dictionaryStore;
    }

    public string GetString(string stringName, string locale)
    {
        return _dictionaryStore.GetLocalizedString(stringName, locale);
    }
}

现在，处理语言环境。我们定义一个接口来获取用户的当前语言环境。隔离这一点很重要，因为在用户计算机上运行的程序可以从进程中读取语言环境，但是在网站上，用户的语言环境可能来自与其用户关联的数据库字段。

ILocaleProvider.cs

public interface ILocaleProvider
{
    string GetCurrentLocale();
}

还有一个默认实现，它使用该过程的当前区域性，因为此示例是一个控制台应用程序：

class DefaultLocaleProvider : ILocaleProvider
{
    public string GetCurrentLocale()
    {
        return CultureInfo.CurrentCulture.Name;
    }
}

我们程序的其余部分实际上并不关心是否要提供本地化的字符串，因此我们可以将本地化查找隐藏在接口后面：

IStringProvider.cs

public interface IStringProvider
{
    string GetString(string name);
}

我们的StringProvider实现负责使用提供的实现ILocaleStringProvider并ILocaleProvider返回本地化的字符串

DefaultStringProvider.cs

public class DefaultStringProvider : IStringProvider
{
    private readonly ILocaleStringProvider _localeStringProvider;
    private readonly ILocaleProvider _localeProvider;
    public DefaultStringProvider(ILocaleStringProvider localeStringProvider, ILocaleProvider localeProvider)
    {
        _localeStringProvider = localeStringProvider;
        _localeProvider = localeProvider;
    }

    public string GetString(string name)
    {
        return _localeStringProvider.GetString(name, _localeProvider.GetCurrentLocale());
    }
}

最后，我们有程序入口点，该入口提供合成根，并获取字符串，并将其打印到控制台：

Program.cs

class Program
{
    static void Main(string[] args)
    {
        var container = new DependencyProvider();

        container.Register<IStringHasher, Sha512StringHasher>();
        container.Register<IStringDictionaryStore, EmbeddedXmlStringStore>();
        container.Register<ILocaleProvider, DefaultLocaleProvider>();
        container.Register<ILocaleStringProvider, StringDictionaryStoreLocaleStringProvider>();
        container.Register<IStringProvider, DefaultStringProvider>();

        var consumer = container.Get<IStringProvider>();

        Console.WriteLine(consumer.GetString(Resources.HelloStringName));
    }
}

这就是您编写准备就绪，可识别语言环境的Hello World程序的企业微服务的方式。
