Decoding most of the infrared signals can be easily handled by PIC16C5X microcontrollers. This application note describes how this decoding may be done. The only mandatory hardware for decoding IR signals is an infrared receiver. The use of two types is described here. Both are modular types used often by the consumer electronics industry. The first type responds to infrared signals modulated at about 40 kHz. The second responds to non-modulated infrared pulses and has a restricted range. The hardware costs of each approach will be less than two dollars.

Far too many programmers and software designers consider efficient C++ to be an oxymoron. They regard C++ as inherently slow and inappropriate for performancecritical applications. Consequently, C++ has had little success penetrating domains such as networking, operating system kernels, device drivers, and others.

Displays CPU time usage, the list of processes (can be terminated) and the task which are running (can be close or switch to). Plus a little net traffic monitor and a disk status report.

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

LCS（最长公共子序列）问题可以简单地描述如下： 一个给定序列的子序列是在该序列中删去若干元素后得到的序列。给定两个序列X和Y，当另一序列Z既是X的子序列又是Y的子序列时，称Z是序列X和Y的公共子序列。例如，若X={A，B，C，B，D，B，A}，Y={B，D，C，A，B，A}，则序列{B，C，A}是X和Y的一个公共子序列，但它不是X和Y的一个最长公共子序列。序列{B，C，B，A}也是X和Y的一个公共子序列，它的长度为4，而且它是X和Y的一个最长公共子序列，因为X和Y没有长度大于4的公共子序列。 最长公共子序列问题就是给定两个序列X={x1,x2,...xm}和Y={y1,y2,...yn}，找出X和Y的一个最长公共子序列。对于这个问题比较容易想到的算法是穷举，对X的所有子序列，检查它是否也是Y的子序列，从而确定它是否为X和Y的公共子序列，并且在检查过程中记录最长的公共子序列。X的所有子序列都检查过后即可求出X和Y的最长公共子序列。X的每个子序列相应于下标集{1,2,...,m}的一个子集。因此，共有2^m个不同子序列，从而穷举搜索法需要指数时间。
