题目链接 思路:针对一个数组的操作,即对一个区间。可以用线段树去进行维护。初始化建树,叶子节点的值为1,维护每段区间上各个元素的乘积sum。M yi,将第i个元素的值改为yi。N di,将第di个元素的值改为1。输出即查询区间[1,Q]的sum值。也就是变成了单点更新、区间查询问题。 #includ Read More

数据传输过程中的安全隐患(safe hidden trouble)    数据机密性(security) 明文传输 就像一个传递一个明信片一样在传递过程中所有中转站都可以看到。    数据的完整性(integrity) 数据在传输时中间人有可能将原数据做修改然后再将修改后的数据传给接收者。  &nb

简介限制理论(TOC)是美籍以色列人高德拉特(Eli Goldratt)博士从物理学领域引进到管理学领域形成的,它是Theory Of Constraints的简称,最初它作为一个物理学原理使用,一个简单的原理存在,它是指物理系统的最薄弱环节决定整个系统的产出或者效率,它在物理设计中经常使用到。1984年,高德拉特博士出版了他的第一本小说《目标》,书中运用约束的相关理论帮助一个工厂厂长在较短的时间
