The government of a small but important country has decided that the alphabet needs to be streamlined and reordered. Uppercase letters will be eliminated. They will issue a royal decree in the form of a String of B and A characters. The first character in the decree specifies whether a must come ( B )Before b in the new alphabet or ( A )After b . The second character determines the relative placement of b and c , etc. So, for example, "BAA" means that a must come Before b , b must come After c , and c must come After d . Any letters beyond these requirements are to be excluded, so if the decree specifies k comparisons then the new alphabet will contain the first k+1 lowercase letters of the current alphabet. Create a class Alphabet that contains the method choices that takes the decree as input and returns the number of possible new alphabets that conform to the decree. If more than 1,000,000,000 are possible, return -1. Definition

平均因子分解法，适用于正定矩阵First, let s recall the Definition of the Cholesky decomposition: Given a symmetric positive definite square matrix X, the Cholesky decomposition of X is the factorization X=U U, where U is the square root matrix of X, and satisfies: (1) U U = X (2) U is upper triangular (that is, it has all zeros below the diagonal). It seems that the assumption of positive definiteness is necessary. Actually, it is "positive definite" which guarantees the existence of such kind of decomposition.

Problem Statement You are given a string input. You are to find the longest substring of input such that the reversal of the substring is also a substring of input. In case of a tie, return the string that occurs earliest in input. Definition Class: ReverseSubstring Method: findReversed Parameters: string Returns: string Method signature: string findReversed(string input) (be sure your method is public) Notes The substring and its reversal may overlap partially or completely. The entire original string is itself a valid substring (see example 4). Constraints input will contain between 1 and 50 characters, inclusive. Each character of input will be an uppercase letter ( A - Z ). Examples 0) "XBCDEFYWFEDCBZ" Returns: "BCDEF" We see that the reverse of BCDEF is FEDCB, which appears later in the string. 1)

C++名家精华.chm 我们用早期的C++语言编程。工作的第二天中午，厌烦了读职工手册，于是我写了一个工具类，里面包含一个原始指针作为成员变量： #include "xStruct.h" // Definition of struct X class xWrapper { X* xItem public: xWrapper() : xItem(new X) { } ~xWrapper() { delete xItem } void dump() { /* dumps xItem to cout */ } } 当然了，使用这个类的程序由于内存问题总是时不时的崩溃，因为我违反三个重要设计原则之一：任何时候，只要你提供了析构函数、拷贝构造函数或赋值运算符中的一个，你通常需要三个都提供。([1]) “所以，”我自言自语道，“我必须自己处理拷贝和赋值问题。简单地...auto_ptr有拷贝构造函数和赋值运算符，我可以拿过来用一下。”（你知道早期C++程序库中的auto_ptr，是吗？）

MS2 程序分析 Lldwsw 一：下载MS2.RAR 压缩包解压缩后可以看到如下界面： 第一项为MS2 软件包，第二项为SourceInsight3.0，它是一款非常优秀的C 语言编辑器，目 前各个大公司，比如华为等都用它，手机行业几乎无一例外。它的作用是代替Keil 的编辑 环境，因为Keil 的编辑环境太难看了，并且使用也不方便，用它来看程序，查找函数特别 容易，以下是它的界面： 各位可以看到，它里面不同的关键字的颜色都是不同的，看上去很舒服，最主要的还是它的 查找功能，比如要看MSTimerStart 的函数原型，但不知道他在那个地方，双击函数名，右 击后出现属性，点“Jump to Definition”，就可以看到函数原型，这个功能Keil 下也有，还 有一个Keil 下没有的，就是这个函数被谁调用了，双击函数名，右击后出现属性，点“Jump to Caller”。 具体请参考SourceInsight 使用说明，也就是第四项，第三项是周立功的DP-51 电路图,因为 MS2 的设计本身是不倚赖外设的，所以没有加外部接口，直接用串口来演示，如下图： 大家可以看到liweifeng， test1，test2，test3 在不停的打印，这是四个伪任务，按一定的时 候间隔打印，我们将在后面分析。当然按键等都可以在处理字符串栏中输入，在接收窗口显 示。 以
