不同于用于匹配流量的IP访问列表,IP前缀列表主要是用来指定具体的网络可达的。
前缀列表用来匹配前缀(网段)和前缀长度(子网掩码)。
前缀列表有两个参数很难理解。
下面是普通的前缀列表的参数:ip prefix-list [name] [permit | deny] [prefix]/[len]name为任意的名字或者数字,prefix是指定的路由前缀(网段),len是指定的前缀长度(子网掩码)。
例子如下:ip prefix-list LIST permit 1.2.3.0/24上面的例子中指定匹配网段1.2.3.0,并且指定子网掩码为255.255.255.0,这个列表不匹配1.2.0.0/24,也不匹配1.2.3.4/32ip prefix-list LIST permit 0.0.0.0/0上面的例子指定匹配网段0.0.0.0和子网掩码0.0.0.0。
这个列表用来匹配默认路由。
通常情况下,在使用前缀列表的时候加上“GE”(大于或等于)和“LE”(小于或等于)时比较容易发生混淆。
这是因为当使用“GE”和“LE”时,列表的长度(len)发生了改变。
另外一种前缀列表的参数:ip prefix-list [name] [permit | deny] [prefix]/[len] ge [min_length] le [max_length]name为任意的名字或者数字,prefix是将要进行比较的路由前缀(网段),len 是指从最左边开始的比特位,min_length为最小的子网掩码的值,max_length 为最大的子网掩码的值使用GE和LE,必须满足下面的条件:len < GE <= LE上面的参数很容易混淆,简单的说就是一个匹配前缀或子网的地址的范围。
看下面的例子:ip prefix-list LIST permit 1.2.3.0/24 le 32上面的例子表示前缀1.2.3.0前面的24位必须匹配。
英语前缀后缀词根总表巧记方法Memorizing a comprehensive list of English prefixes, suffixes, and root words can be challenging, but with the right strategies, it can be done effectively. Here are some tips and techniques to help you remember these building blocks of vocabulary:1. Storytelling: Create stories or narratives around the prefixes, suffixes, and root words. For example, imagine a character named "Prefix Pete" who embarks on a journey with "Suffix Sally" to find the meaning of various root words. By creating engaging stories, you can turn the otherwise dry material into something more memorable.2. Rhyming and Alliteration: Use rhyming andalliteration to help you remember words. For instance, you could create a list of words that rhyme with each prefix or suffix, or use alliteration by repeating the same initial letter in a series of related words. This can help you group and associate words more easily.3. Visual aids: Create visual aids like charts, mind maps, or flashcards to help you visualize and organize the information. You can use colors, images, or symbols to make the material more visually appealing and easier to remember.4. Mnemonic devices: Use mnemonic devices, such as acronyms, rhymes, or songs, to help you remember complex words or groups of words. For instance, you could create a song or rhyme to help you remember the meaning of aparticular prefix or suffix.5. Practical application: Try to use the new vocabulary in real-life situations as often as possible. This could be through speaking, writing, or even thinking about how you can apply the words to your daily life. The more you usethe words, the more likely you are to remember them.6. Repetition: Repetition is key to memory retention. Review your list of prefixes, suffixes, and root words regularly, and try to incorporate them into your daily routine. This could be through reading, writing, or evenspeaking about the words on a regular basis.7. Context learning: Place the words in context by learning them in phrases or sentences. This can help you understand the meaning and usage of the words more deeply, and make them easier to remember.8. Interactive learning: Try using interactive learning methods, such as quizzes, games, or discussions, to engage with the material more actively. This can help you solidify your understanding of the prefixes, suffixes, and root words, and make the learning process more enjoyable.9. Mnemonic devices for specific prefixes and suffixes: Here are some examples of mnemonic devices for common prefixes and suffixes:Prefix "re-": Imagine a person doing something again and again (redo, remake, return).Prefix "un-": Think of something being undone or taken away (undo, unpack, unpack).Suffix "-able": Think of something that can be done or achieved (readable, loveable,可信的).Suffix "-less": Imagine something being without or lacking something (careless, hopeless,无尽的).10. Connect to emotions: Try to create an emotional connection to the words you are learning. For instance, if a particular prefix or suffix reminds you of a funny story or experience, use that to help you remember it. Emotional connections can be powerful mnemonic tools.By using these tips and techniques, you can turn the task of memorizing prefixes, suffixes, and root words into a more enjoyable and effective learning experience. With regular practice and repetition, you'll be able to build a rich vocabulary that will enhance your understanding and expression in English.。

前缀列表(prefix-list)讲解不同于用于匹配流量的IP访问列表,IP前缀列表主要是用来指定具体的网络可达的。
前缀列表用来匹配前缀(网段)和前缀长度(子网掩码)。
前缀列表有两个参数很难理解。
下面是普通的前缀列表的参数:ip prefix-list [name] [permit | deny] [prefix]/[len]name为任意的名字或者数字,prefix是指定的路由前缀(网段),len是指定的前缀长度(子网掩码)。
例子如下:ip prefix-list LIST permit 1.2.3.0/24上面的例子中指定匹配网段1.2.3.0,并且指定子网掩码为255.255.255.0,这个列表不匹配1.2.0.0/24,也不匹配1.2.3.4/32ip prefix-list LIST permit 0.0.0.0/0上面的例子指定匹配网段0.0.0.0和子网掩码0.0.0.0。
这个列表用来匹配默认路由。
通常情况下,在使用前缀列表的时候加上“GE”(大于或等于)和“LE”(小于或等于)时比较容易发生混淆。
这是因为当使用“GE”和“LE”时,列表的长度(len)发生了改变。
另外一种前缀列表的参数:ip prefix-list [name] [permit | deny] [prefix]/[len] ge [min_length] le [max_length]name为任意的名字或者数字,prefix是将要进行比较的路由前缀(网段),len是指从最左边开始的比特位,min_length为最小的子网掩码的值,max_length为最大的子网掩码的值。
使用GE和LE,必须满足下面的条件:len < GE <= LE上面的参数很容易混淆,简单的说就是一个匹配前缀或子网的地址的范围。
看下面的例子:ip prefix-list LIST permit 1.2.3.0/24 le 32上面的例子表示前缀1.2.3.0前面的24位必须匹配。
由于110版暗黑没中文修改器,所以只能使用老外制作的这个鸟语版的(-_-)!这款修改器的原理是在启动了游戏程序的基础上进行文件编辑的,所以想汉化是不太容易的的。
1、装备的生成。
按快捷键S从里边拿出自己想要编辑的装备。
上边的红圈表示防具,前边那个是武器,绿圈是魔法和任务物品,最后的兰色的是套装。
2、编辑物品。
把光标放到装备上,右键->编辑。
这里是最关键的,由于游戏读取的是2进制编码,所以这里的修改就比较麻烦黄色框:属性的名字。

装备的修改2-------------------------------详细:在编辑界面中,左上角的方框是你的装备,在装备框的右方从上到下依次是“代码说明”、“代码长度(或属性名、码)”、“属性值”三个长方形框。
然后再下方是一个较大的框“ITEM”,框里面那些10010001之类的就是该物品的代码在“ITEM”这几个字的右方是几个小方块,从左到右第一个小方块“CLEAN ITEM”的作用是清除无用代码,第二个“DELETE PROPERTIES”的作用是删除所有附加的属性(加的属性不满意了可以将其清除,但要注意这是所有属性全部清除),第三个“SET SOCKETS”的作用是设置物品的孔数第4、5、6、7 个小方块都没用,第8个也就是最右边一个小方块“REFRESH ITEM”的作用是刷新物品,把各个属性的代码以合适的顺序排列好。
在“ITEM”大框的下面是一个小长条,没什么用,看都不用看,它就相当于WINDOWS里面状态栏的作用,显示光标当前所在位置和该物品总代码长度以及你选择的代码范围。

The Longman Defining VocabularyWords used in the definitions in this dictionaryAll the definitions in this dictionary have been written using the words in this list. If a definition includes a word that is not in the list, that word is shown in small capital letters.The Defining Vocabulary has been carefully chosen after a thorough study of all the well-known frequency lists of English words. Furthermore, only the most common and ‘entral’ meanings of the words in the list have actually been used in definitions. We have also used a special computer program that checks every entry to ensure that words from outside the Defining Vocabulary do not appear in definitions.Word class restrictionsFor some words in the list, a word class label such as n or adj is shown. This means that this particular word is used in definitions only in the word class shown. So anger, for example, is used only as a noun and not as a verb. But if no word class is shown for a word, it can be used in any of its usual word classes: answer, for example, is used in definitions both as a noun and as a verb.Compound wordsDefinitions occasionally include compound words formed from words in the Defining Vocabulary, but this is only done if the meaning is completely clear. For example, the word businessman (formed from business and man) is used in some definitions.Prefixes and suffixesThe main list is followed by a list of common prefixes and suffixes. These can be added to words in the main list to form derived words, provided the meaning is completely clear. For example, the word nervousness (formed by adding -ness to nervous) is used in some definitions.Phrasal verbsPhrasal verbs formed by combining words in the Defining Vocabulary (for example, put up with) are not used in definitions in the dictionary, except in a very small number of cases where the phrasal verb is extremely common and there is no common equivalent. So, for example, give up (as in give up smoking) and take off (as in the plane took off) are occasionally used.Proper namesThe Defining Vocabulary does not include the names of actual places, nationalities, religions, and so on, which are occasionally mentioned in definitions.Pearson Education Limited 1999a abbreviation abilityableaboutabove adv, prep abroad absence absent adj accept

list erase函数List erase函数是一种常见的列表操作函数,用于删除列表中指定位置的元素。
该函数通常用于编程语言中,可以在列表中删除指定索引位置的元素,改变列表的长度和结构。
本文将详细介绍list erase 函数的使用方法和注意事项。
在使用list erase函数时,首先需要明确要删除的元素的索引位置。
索引位置从0开始计数,表示元素在列表中的位置。
要删除指定位置的元素,可以使用list的erase方法,并传入要删除的元素的迭代器作为参数。
例如,要删除列表中的第三个元素,可以使用以下代码:```my_list.erase(my_list.begin() + 2);```这行代码会删除my_list列表中索引为2的元素。
需要注意的是,erase方法的参数应该是要删除元素的迭代器,而不是索引位置本身。
因此,需要使用begin()方法获取列表的起始位置,并通过加法运算符将索引位置转换为对应元素的迭代器。
在使用list erase函数时,还需要注意以下几点:1. 删除元素后,列表的长度会减少。
因此,在删除元素后继续使用之前的迭代器可能会导致未定义的行为。
建议在删除元素后更新迭代器,或使用迭代器失效前的备份。
2. 要删除多个连续的元素,可以使用erase方法的迭代器范围参数。
例如,要删除列表中从第二个元素到第五个元素(包括第二个和第五个元素),可以使用以下代码:```my_list.erase(my_list.begin() + 1, my_list.begin() + 5);```这行代码会删除my_list列表中索引从1到4的元素。
3. 如果要删除的元素不存在于列表中,erase方法不会产生任何效果。
因此,在使用erase方法之前,建议先检查要删除的元素是否存在于列表中。
4. list erase函数的时间复杂度为O(n),其中n是列表的长度。
这是因为删除元素后,列表中的所有后续元素都需要向前移动一位。
filter的用法搭配一、filter函数的基本介绍filter函数是Python内置的一个高阶函数,它接受一个函数和一个可迭代对象作为参数,用于过滤出满足条件的元素并返回一个新的可迭代对象。
二、filter函数的语法和返回值filter函数的语法如下所示:filter(function, iterable)其中,function是一个函数,用于判断iterable中的每个元素是否满足条件。
iterable是一个可迭代对象,可以是列表、元组、集合或字符串。
filter函数返回一个filter对象,可以使用list()函数将其转换为列表。
三、使用filter函数的示例下面通过几个示例来演示filter函数的用法。
示例1:过滤出偶数numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]def is_even(n):return n % 2 == 0result = filter(is_even, numbers)even_numbers = list(result)print(even_numbers) # 输出:[2, 4, 6, 8, 10]在这个示例中,我们定义了一个is_even函数,用于判断一个数是否为偶数。
然后使用filter函数过滤出列表numbers中的所有偶数并将其转换为列表even_numbers。
示例2:过滤出长度大于等于5的字符串strings = ["apple", "banana", "cherry", "date", "elderberry"]def is_long(s):return len(s) >= 5result = filter(is_long, strings)long_strings = list(result)print(long_strings) # 输出:['banana', 'cherry', 'elderberry']在这个示例中,我们定义了一个is_long函数,用于判断一个字符串的长度是否大于等于5。

下面是普通的前缀列表的参数:ip prefix-list [name] [permit | deny] [prefix]/[len]name为任意的名字或者数字,prefix是指定的路由前缀(网段),len是指定的前缀长度(子网掩码)。
例子如下:ip prefix-list LIST permit 1.2.3.0/24上面的例子中指定匹配网段1.2.3.0,并且指定子网掩码为255.255.255.0,这个列表不匹配1.2.0.0/24,也不匹配1.2.3.4/32ip prefix-list LIST permit 0.0.0.0/0上面的例子指定匹配网段0.0.0.0和子网掩码0.0.0.0。
这个列表用来匹配默认路由。
通常情况下,在使用前缀列表的时候加上“GE”(大于或等于)和“LE”(小于或等于)时比较容易发生混淆。
这是因为当使用“GE”和“LE”时,列表的长度(len)发生了改变。
另外一种前缀列表的参数:ip prefix-list [name] [permit | deny] [prefix]/[len] ge [min_length] le [max_length]name为任意的名字或者数字,prefix是将要进行比较的路由前缀(网段),len是指从最左边开始的比特位,min_length为最小的子网掩码的值,max_length为最大的子网掩码的值使用GE和LE,必须满足下面的条件:len < GE <= LE上面的参数很容易混淆,简单的说就是一个匹配前缀或子网的地址的范围。
看下面的例子:ip prefix-list LIST permit 1.2.3.0/24 le 32上面的例子表示前缀1.2.3.0前面的24位必须匹配。
IP prefix-list及與ACL, route-map的比較Cisco 2011-03-12 23:07:43 阅读6 评论1 字号:大中小订阅下面是一條標準的prefix-list, 我們對其進行分析:ip prefix-list 100 permit 128.0.0.0/2 ge 16 le 24ge=greater or equal le=less or equal1、R1(config)#ip prefix-list ?WORD Name of a prefix listsequence-number Include/exclude sequence numbers in NVGENR1(config)#ip prefix-list 100 ?deny Specify packets to rejectdescription Prefix-list specific descriptinpermit Specify packets to forwardseq sequence number of an entry基本的格式上和ACL還是差不多的。
2、關鍵的對於128.0.0.0/2的這個/2代表了什麼含義?128.0.0.0 換成2進制數為10 000000 00000000 00000000 00000000/2代表只對前面的2位必須match,即,前2位是不變的,在不帶ge 16 le 24的情況下,prefix-list裏的128.0.0.0/2 代表的是一個範圍,是從128.0.0.0/7到191.255.255.252/30,而加上ge 16 le 24 的意思就是ip地址mask從/16到/24下面是幾個例:prefix-list 100 permit 0.0.0.0/0 代表的是所有路由prefix-list 100 permit 0.0.0.0/32 代表的是預設路由prefix-list 100 permit 0.0.0.0/0 ge 32代表的是所有host路由3、在ACL裏,128.0.0.0/2是什麼含義?下面是128.0.0.0的2進表達表示10 000000 00000000 00000000 00000000在ACL裏,permit 128.0.0.0/2,那就沒意義了,要使用128.0.0.0,最小的mask 位數為7位(2的7次是128)4、其實ACL也有方法定義一個範圍,以實現類似prefix-list的功能。
netmask 和prefix 的对应关系Title: Understanding the Correspondence between Netmask and PrefixIntroduction:In computer networking, the concepts of netmask and prefix play a crucial role in determining network addressing and routing. They are used to define the network address and subnetting capabilities of a network. This article aims to provide a comprehensive understanding of the correspondence between netmask and prefix and their significance in network configuration.1. Definition of Netmask:A netmask, short for network mask, is a 32-bit number that is used to divide an IP address into network and host portions. It essentially determines the size of the network by identifying which bits in an IP address belong to the network and which bits belong to the host. The netmask is represented in decimal dot notation, such as 255.255.255.0, where each octet represents 8 bits of the netmask.2. Understanding Prefix:Prefix, also known as CIDR notation, is an alternative way to represent subnet masks. CIDR stands for Classless Inter-Domain Routing, used to divide IP addresses into smaller subnets and allocate them efficiently. It specifies the number of significant bits from the left in the network part of an IP address. A prefix is indicated by appending a forward slash (/) followed by the number of significant bits to the IP address, such as 192.168.0.0/16.3. Relationship between Netmask and Prefix:Netmask and prefix are closely related. The prefix length is equal to the number of contiguous 1 bits in the netmask. For example, a netmask of 255.255.255.0(11111111.11111111.11111111.00000000) has 24 contiguous 1 bits. Thus, its corresponding prefix length is /24.4. Calculating Prefix from Netmask:To derive the prefix from the netmask, count the number of contiguous 1 bits in the binary representation of the netmask. For instance, a netmask of 255.255.255.0 has 24 contiguous 1 bits. Hence, the prefix for this netmask would be /24.5. Conversion of Prefix to Netmask:Conversely, to convert a prefix to its corresponding netmask, count the number of significant bits and put that many 1 bits at the leftmost positions of a 32-bit number, followed by the remaining bits as 0. For example, a prefix of /27 indicates 27 significant bits. Thus, the corresponding netmask would be11111111.11111111.11111111.11100000, which in decimal dot notation is 255.255.255.224.6. Significance in Network Configuration:The correspondence between netmask and prefix is essential for determining subnet boundaries and establishing the number of available hosts in a network. Network administrators use this information to design efficient network architectures, allocate IP addresses, and enable routing protocols to classify network traffic.7. Benefits of Prefix in Comparison to Netmask:CIDR notation, represented by prefix, offers several advantages over traditional netmask representation:a. Flexibility: Prefix notation allows for more precise allocation of IP addresses, as it can define subnets of varying sizes.b. Address conservation: Prefix notation conserves IP address space by allowing networks to be divided into smaller subnets,reducing wastage.c. Simplified routing: CIDR simplifies routing decisions by aggregating IP address blocks into larger prefixes, reducing the size of routing tables.Conclusion:Netmask and prefix are critical elements in network configuration, determining the division of IP addresses into network and host portions. Understanding their correspondence and significance enables efficient subnetting and routing decisions. Network administrators must be adept at calculating and utilizing netmasks and prefixes to optimize network resources and address allocation effectively. This comprehensive understanding of netmask and prefix relationship helps in building robust and scalable networks.。
