Sas学习笔记
Sas学习笔记人文社会科学学院高等教育学专业张宁S100081674整个SAS程序结构可以分为两个部分，数据data步与过程proc步。
data步1：输入数据（包括手动输入数据、从文本文件中导入数据）a使用手动方法输入数据基本形式是：Data 数据集；Input 变量名（包括格式设置）；/*在input语句中需要指定的格式必须和cards中数据的格式一致，需要考虑字符型与数值型数据的不同，以及是否是标准数据，根据实际情况调整数据格式设定*//* 同时在读入数据的时候，需要参考数据的形式，指定输入的起始位置与字符数，包括使用@指针控制、指定起始列终止列、指定字符数等*/其他语句；/*循环语句，选择语句等*//*sas表达式：sas运算符（包括算数、比较、逻辑）sas函数（包括算数函数、常用函数等）*/Cards ；数据；/*其中数据之间默认为空格作为分隔符，如果分隔符为其他符号，则要在input语句中指定delimiter=‘’*/Run；b使用文本文件导入法基本形式是：Data 数据集；变量属性设定；Infile‘文件地址’（firstobs=，obs= ，missover）；Input；其他语句；/*循环语句，选择语句,sas表达式*/Run；当然输入数据的时候可以直接使用sas导入数据选项，根据情况设定形式，导入数据。
c总之在data步中常见的语句有：DA TA语句PUT语句——输出语句SET语句——读取观测语句ATTRIB语句——设定变量属性赋值语句——计算SAS表达式，给变量赋值DROP语句——删除变量语句KEEP语句——保留变量语句IF语句——条件语句DO-END语句——循环语句DELETE语句——删除语句OUTPUT语句——输出到数据集语句COMMENT语句——注释语句ARRAY语句——数组语句在实际操作中，可以灵活的使用这些语句实现数据处理。

AS3.0学习笔记_原创
Action Script 学习笔记1 在AS里，数据类型分为两种，基本数据类型和复杂数据类型。
2 基本（简单）数据类型分为：int：32位整数型，运行时比number占的内存要小，属于Number类型number：64位整数型，可以表示长整形，也可以表示浮点类型，功能多，但占内存大String：字符串数据类型uint：无符号，也就是无正负整形。
这里的符号是在二进制码中的符号，我们知道，对一般的整形，二进制码中的第一位是符号位，而unit类型舍去了这个符号位，第一位还可以继续赋值，无正负，全部视为正数。
我们一般用unit来作为颜色值。
属于Number类型。
Boolean：布尔数据类型，即逻辑数据类型Null：空值。
和“”的区别是：null状态下，只在栈内存中开辟了一个空间存放所声明的变量；但若为空值“”，则会另辟在内存中另辟一个地址，用来存放“”，也就是消耗了两块内存区域。
void：未定义数据类型，3 除了基本数据类型外，其他都是复杂数据类型，可以概括为：String，Object，Array，对象等。
即：复杂数据类型都是由基本数据类型组成的，或者由其他复杂数据类型组成的。
AS3.0中包含了大量内建的复杂数据类型，我们也可以自己设置复杂数据类型。
4 凡是继承DisplayObjectContainer的类的子类，都属于容器。
简单得说，容器就是拥有子集列表的一个对象。
5 Sprite类是显示列表构造块。
是一个可以显示图形同时可以包含子项的显示列表节点。
因此，Sprite是一种容器，我们可以理解它为一张画布，有了它我们可以画各种图形，也可以把画好的东西贴上去，通过不同的组件拼凑出一张完整的图案。
代码见：代码/testAS3.0_7.2-7.6/com/xbax/as3/HelloWorld6 如果不使用Sprite.addChild()等方法，则不会将该组件添加到画板上，自然我们就看不到任何显示了。
Android 反编译 -smali语法
Android 反编译 -smali语法前言前面我们有说过android反编译的工具，如何进行反编译。
反编译后可以得到jar或者得到smali文件。
Android采用的是java语言进行开发，但是Android 系统有自己的虚拟机Dalvik,代码编译最终不是采用的java的class，而是使用的smali。
我们反编译得到的代码，jar的话可能很多地方无法正确的解释出来，如果我们反编译的是smali则可以正确的理解程序的意思。
因此，我们有必要熟悉smali语法。
类型的表示java里面包含两种类型，原始类型和引用类型(包括对象)，同时映射到smali也是有这两大类型。
原始类型1.V void (只能用于返回值类型)2.Z boolean3. B byte4.S short5. C char6.I int7.J long8. F float9. D Double对象类型1.Lpackage/name/ObjectName; 相当于java中的.ObjectNameL 表示这是一个对象类型package/name 该对象所在的包ObjectName 对象名称; 标识对象名称的结束数组的表示[I 表示一个int型的一维数组，相当于int[]；增加一个维度增加一个[,如[[I表示int[][]数组每一个维度最多255个;对象数组表示也是类似，如String数组的表示是[Ljava/lang/String寄存器与变量java中变量都是存放在内存中的，android为了提高性能，变量都是存放在寄存器中的，寄存器为32位，可以支持任何类型，其中long和double是64为的，需要使用两个寄存器保存。
寄存器采用v和p来命名v表示本地寄存器，p表示参数寄存器，关系如下如果一个方法有两个本地变量，有三个参数1.v0 第一个本地寄存器2.v1 第二个本地寄存器3.v2 p0 (this)4.v3 p1 第一个参数5.v4 p2 第二个参数6.v5 p3 第三个参数当然，如果是静态方法的话就只有5个寄存器了，不需要存this了。
smali基础
Smali基础1.背景知识使用Apktool反编译apk 文件后，会在反编译工程目录下生成一个smali 文件夹，里面存放着所有反编译出的smali 文件，这些文件会根据程序包的层次结构生成相应的目录，程序中所有的类都会在相应的目录下生成独立的smali 文件。
smali 文件的代码通常情况下比较长，而且指令繁多，在阅读时很难用肉眼捕捉到重点。
无论是普通类、抽象类、接口类或者内部类，在反编译出的代码中，它们都以单独的smali文件来存放。
每个smali 文件都由若干条语句组成，所有的语句都遵循着一套语法规范。
2.文件头在smali 文件的头3 行描述了当前类的一些信息，格式如下。
.class < 访问权限> [ 修饰关键字] < 类名>.super < 父类名>.source <源文件名>2.1.数据类型在smali中，数据类型和Android中的一样，只是对应的符号有变化：B---byteC---charD---doubleF---floatI---intJ---longS---shortV---voidZ---boolean[XXX---arrayLxxx/yyy---object这里解析下最后两项，数组的表示方式是：在基本类型前加上前中括号“[”，例如int数组和float数组分别表示为：[I、[F；对象的表示则以L作为开头，格式是LpackageName/objectName;（注意必须有个分号跟在最后），例如String对象在smali中为：Ljava/lang/String;，其中java/lang对应ng包，String就是定义在该包中的一个对象。
或许有人问，既然类是用LpackageName/objectName;来表示，那类里面的内部类又如何在smali中引用呢？答案是：LpackageName/objectName$subObjectName;。
SAM学习笔记
对一个endposendpos等价类中长度最长的所有位置再向前添加一个字符那么由于性质2这个等价类必定会被分割成若干个新的endposendpos等价类一开始有11个点每次划分最多只能产生22个新节点由于初始endposendpos集合大小才nn最多划分n?1n?1次所以自然只会有2n?12n?1个状态
Loading [MathJax]/jax/element/mml/optable/GeneralPunctuation.js
考虑到\textbf{endpos}总个数最多才2n个，又通过性质(1)注意到对于两个\textbf{endpos}相同的状态所有转移边也相同，于是自然想到把每个\textbf{endpos}等价类缩成一个点，形成了一 个\operatorname{DAG}：
增量法构造\textbf{sam} 强行背板子部分 具体过程：每次插入一个字符c的时候，新增节点o，从上一次新增的状态p，不断跳link，沿途所有状态全部链向o，直到某个状态u有转移边ch(q,c)指向点v，直接将link(o)链向v，如果不满足性 质len(v)=len(u)+1，那就再新建一个节点q，使得len(v)=len(u)+1，link(q)=link(v)+1，然后把o和v连到q上然后往上跳，过程中把全部指向v的转移边全指向q。 结合代码理解： int fa[maxn<<1],ch[maxn<<1][28],psiz[maxn<<1],len[maxn<<1]; int lstp=1,cnt=1; inline void extend(int c){ int p=lstp,np=lstp=++cnt; len[np]=len[p]+1,psiz[np]=1; for (;p&&!ch[p][c];p=fa[p]) ch[p][c]=np; if(!p){

samil语法
samil语法
由于“samil”是一种编程语言，因此它有其特定的语法规则。
以下
是“samil”语言的语法特点：
1. 表达式：表达式可以是变量、常量、字符串、函数、操作符和括
号的组合。
例如，“a=1+2”、“b=4*5-6”、“c=fun(a,b)” 等。
2. 变量：变量名必须以字母或下划线开头，可以包含数字、字母和
下划线。
例如，“a”、“var_1”、“myVar” 等。
3. 常量：常量是一些固定的数值或字符串，例如：“3.14159”、
“'hello world'”等。
4. 数据类型：samil支持各种不同的数据类型，包括整数、浮点数、布尔值、字符串、数组、哈希表等。
5. 函数：函数由关键字“func”后跟函数名和参数列表组成。
函数
可以返回一个值或不返回任何值。
例如：“func sum(a, b) { return
a+b; }”、“func print(s) { console.log(s); }”等。
6. 语句：语句是程序中执行某些操作的行为单元。
samil支持循环
语句、条件语句、跳转语句等。
例如：“if (a>b) { print('a is
greater than b'); }”、“for (i=0; i<10; i++) { print(i); }”、“while (i<10) { i++; }”等。
总之，samil语法是比较简单易懂的，但需要注意细节。
程序员需要
认真熟悉语言规范，才能写出高效、健壮的代码。

Dalvik opcodesAuthor: Gabor PallerVx values in the table denote a Dalvik register. Depending on the instruction, 16, 256 or 64kregisters can be accessed. Operations on long and double values use two registers, e.g. a doublevalue addressed in the V0 register occupies the V0 and V1 registers.Boolean values are stored as 1 for true and 0 for false. Operations on booleans are translated into integer operations.All the examples are in hig-endian format, e.g. 0F00 0A00 is coded as0F, 00, 0A, 00 sequence.Note there are no explanation/example at some instructions. This means that I have not seen thatinstruction "in the wild" and its presence/name is only known from Android opcode constant list.Opcode(hex)Opcode name Explanation Example00 nop No operation 0000 - nop01 move vx,vy Moves the content of vy into vx.
