后缀数组是处理字符串的有力工具。后缀数组是后缀树的一个非常精巧的
替代品，它比后缀树容易编程实现，能够实现后缀树的很多功能而时间复杂度也
并不逊色，而且它比后缀树所占用的内存空间小很多。可以说，在信息学竞赛中
后缀数组比后缀树要更为实用。本文分两部分。第一部分介绍两种构造后缀数组
的方法，重点介绍如何用简洁高效的代码实现，并对两种算法进行了比较。第二
部分介绍后缀数组在各种类型题目中的具体应用。
Suffix array is a powerful tool for dealing with strings. Suffix array suffix tree is a very delicate
Alternatives, it is easier than programming suffix tree, the suffix tree can achieve a lot of functions and the time complexity is
Not inferior, but it is much smaller than the suffix tree occupies memory space. We can say that in informatics contest
Suffix array to be more practical than the suffix tree. This article in two parts. The first part describes two suffix array construction
The method focuses on how to use simple and efficient implementation of the code, and the two methods were compared. Second
Section describes the specific application types suffix array of topics. (2014-06-10, C++, 300KB, 下载7次)
哈夫曼树是一种树形结构，用哈夫曼树的方法解编程题的算法就叫做哈夫曼算法。树并不是指植物，而是一种数据结构，因为其存放方式颇有点象一棵树有树叉因而称为树。 最简哈夫曼树是由德国数学家冯。哈夫曼 发现的，此树的特点就是引出的路程最短。 概念理解：1.路径 从树中一个节点到另一个节点之间的分支构成这两个节点之间的路径。2.路径长度 路径上的分支数目称作路径长度。
Huffman tree is a tree structure, Huffman tree algorithm method to solve programming problems is called the Huffman algorithm. Tree does not mean the plant, but a data structure, because of its storage methods have quite a bit like a tree which is called Shucha tree. Minimalist Huffman tree by the German mathematician Von. Huffman discovered feature of this tree is drawn from the shortest. Understanding of the concept: a path from one node to the tree branch paths between other nodes between the two nodes. 2 the number of branches on the path length of the path is called the path length.

动态规划问题。给定一个整数的二维数组，由其中若干邻近元素构成的矩形称为子数组。 编程计算所有子数组元素之和的最大值。输入为整数n，及n^2个数，输出为所有子数组元素之和的最大值
Dynamic programming problem.Given a two-dimensional array of positive and negative integers, a sub-rectangle is any contiguous sub-array of size 1*1 or greater located within the whole array. The sum of a rectangle is the sum of all the elements in that rectangle. In this problem the sub-rectangle with the largest sum is referred to as the maximal sub-rectangle.

程序用C++模拟了操作系统中的三种最典型的简单的静态进程调度算法；先由用户动态输入生成模拟进程，使用了26种可供用户选择的典型语句（包括循环、选择结构），可处理整型、布尔型与字符型三种数据与表达式计算；程序编制时主要采用的编程技术是：用语句链表记录进程语句，并用PCB链表,就绪队列链表,阻塞队列链表,执行队列链表,结束队列链表等数据表示进程处理过程中的相互关系，由于静态数据结构不适合处理数据量大小不定的数据，而动态队列结构适合于处理数据量大小可变数据的处理，因此在程序中采用动态链表对这些数据进行处理；使用信号量、P.V.操作实现进程的同步与互斥，模拟进程在操作系统中的运行
