Description: 练习程序，问题如下：进行高精度整数的加、减、乘运算。输入两个十进制大整数M和N（M、N最长可达50位），计算运算结果并输出。【输入形式】标准输入上依次分行输入以下内容：1.第一行输入第一个大整数M。M可能带有负号，后面是最长可达50位的数字序列。2.第二行只有一个字符，可以是“+”、“-”、“*”，分别代表加、减、乘三种运算符。3. 第三行输入大整数N，格式与M相同M、N均不带有前缀的多余的0【输出形式】在标准输出上打印运算结果，输出一行字符序列，是大整数M和N和运算结果。如果该运算结果是正数，则直接输出各位数字序列；如果是负数，则首先要输出负号。各位数字紧密输出，不带有前缀的多余的0。-practice procedures, as follows : high-precision integer for the addition, subtraction, multiplication. The importation of two decimal integer big M and N (M, N up to a maximum of 50), the calculated results of operations and output. Entry forms : standard input on the importation of branches were the following : 1. The first line inputs, a large integer M. M may have negative, is back up to 50 digital sequence. 2. Only a second line of characters could be "","-","*", respectively, plus or minus, by three operators. 3. The third line inputs large integer N, M and the same format M, N are not redundant with the prefix 0 output-- in the form of print on standard output Operational result, the output sequences of characters here is the large integers M and N and

Description: 此次课程设计我的设计题目是：判别后缀表达式。其具体要解决的问题是：
（1）假设表达式由单字母变量和双目四则运算符构成；
（2）从键盘输入任意一个非空的表达式；
（3）利用栈，判别输入的表达式是否是一个正确的后缀表达式；
（4）把正确的后缀表达式转换为前缀表达式；
（5）测试用例自己设计。
-current curriculum design I design entitled : distinguishing suffix expression. To solve their specific problems are : (a) It is assumed that the expression of single-letter variable binocular and four Operators composition; (2) from the keyboard input an arbitrary non-empty expression; (3) using stack, Discriminant importation of whether the expression is a correct expression of the suffix; (4) the correct conversion of expression suffix prefix expression; (5) The test case of its own design.

Description: 表达式类型的实现:
1、 一个表达式和一颗二叉树之间，存在着自然的对应关系。
2、 假设算术表达式Expression内可以含有变量（a～z）、常量（0～9）和二元运算符（＋，－，*，/，^）。实现一下操作。
（1） ReadExpr(E)——以字符序列的形式输入语法正确的前缀表示式并构造表达式E。
（2） WritrExpr(E)——用带括弧的中缀表示式输出表达式E。
（3） Assign(V,c)——实现对变量V的赋值(V=c),变量的初值为0。
（4） Value(E)——对算术表达式E求值。
（5） CompoundExpr(P,E1,E2)——构造一个新的复合表达式（E1）P (E2)。
-Realize the type of expression: one, an expression, and between a binary tree, there is a natural correspondence between. 2, assuming that the arithmetic expression Expression can contain variables (a ~ z), constant (0 ~ 9) and binary operators ( ,-,*,/,^)。 You realize the operation. (1) ReadExpr (E)- sequence of characters in the form of input grammar correct prefix expressions and tectonic expression of E. (2) WritrExpr (E)- used within parentheses express output infix expression E. (3) Assign (V, c)- realize the value V of the variables (V = c), variable initial value is 0. (4) Value (E)- on the arithmetic expression E is evaluated. (5) CompoundExpr (P, E1, E2)- Construction of a new composite expression (E1) P (E2).

Description: 关于后缀数组的文件
本文介绍后缀数组的基本概念、方法以及应用。
首先介绍O(nlogn)复杂度构造后缀数组的倍增算法，接着介绍了配合后缀
数组的最长公共前缀 LCP（Longest Common Prefix）的计算方法，并给出一个
线性时间内计算height 数组（记录跨度为1 的LCP 值的数组）的算法。为了让
读者对如何运用后缀数组有一个感性认识，还介绍了两个应用后缀数组的例子：
多模式串的模式匹配（给出每次匹配O(m+logn)时间复杂度的算法）以及求最
长回文子串（给出O(nlogn)时间复杂度的算法）。最后对后缀数组和后缀树作了
一番比较。-about suffix array
