数据结构：队列程序-data structure : queue procedures

题目：设计一个题目，演示用算符优先法对算术表达式求值的过程。 概要设计 1、顺序扫描中缀算术表达式，当读到数字时直接将其送至输出队列中； 2、当读到运算符时，将栈中所有优先级高于或等于该运算符弹出，送至输出队列中，再将当前运算符入栈； 3、当读入左括号时，即入栈； 4、当读到右括号时，将靠近栈顶的第一个左括号上面的运算符全部一次弹出，送至输出队列中，再删除栈中的左括号。 5、使用VS栈来存储读入的操作和运算结果，然后进行数字字符到数值的转换。 -Title: Design of a topic, presentation operator priority method with arithmetic expression evaluation process. Summary of design 1, the order of scanning arithmetic infix expressions, when they read numbers directly to the output queue 2, when they read operator, it will stack all priority higher than or equal to the operator pop-up , sent to the output queue, and then the current operator入栈 3, when read left brackets, that is, when入栈 4, when they read the right brackets, it will be near the Top-left of the first operator in brackets above All a pop-up, sent to the output queue, and then delete stacks of left brackets. 5, the use of VS stack to store read operation and computing the results of numeric characters and then proceed to the numerical co

数据库系统设计课程作业设计并实现一个精简型单用户SQL引擎(DBMS)MiniSQL，允许用户通过字符界面输入SQL语句实现表的建立/删除；索引的建立/删除以及表记录的插入/删除/查找。 通过对MiniSQL的设计与实现，提高学生的系统编程能力，加深对数据库系统原理的理解。

问题描述： 给定n个石子，其重量分别a1,a2,a3...an,要求将其划分成m份，每一份的划分费 义为这份石了中最大重量与最小重量的差的平方。总划分费用等丁m份划分费用之和。 编程任务 对于给定的n个石子，求一种划分方案，使得总划分费用最小。-Description of the problem: Given n-stones, its weight, respectively a1, a2, a3 ... an, asked that it be divided into m copies, each of the division of costs defined as the weight of the stone of the largest and the smallest weight difference the square. Small m the total costs were divided into the sum of the cost. Programming tasks for a given n-stones, seek a kind of division, making the total cost of the smallest division.
