在信息工程中指针是一个用来指示一个内存地址的计算机语言的变量或中央处理器(CPU)中寄存器(Register)【用来指向该内存地址所对应的变量或数组】。指针一般出现在比较接近机器语言的语言,如汇编语言或C语言。面向对象的语言如Java一般避免用指针。指针一般指向一个函数或一个变量。在使用一个指针时,一个程序既可以直接使用这个指针所储存的内存地址,又可以使用...
(a)What is Algorithm and Data Structure? Algorithm: Algorithms are basically methods or recipes for solving various problems. To write a program to solve some problems, we first need to know a suitable algorithm. 算法导论:非形式的说,算法就是任何良定义的计算过程,该过程取某个值或者值的集合作为...

in this text students look at specific problems and see how careful implementations can reduce the time constraint for large amounts of data from 16 years to less than a second. Therefore, no algorithm or data structure is presented without an explanation of its running time. In some cases, ...

除了这两个之外,当然还有很多其他加密算法,比如DES(Data Encryption Standard,数据加密标准)、AES(Advanced Encryption Standard,高级加密标准)。 前面我讲到的哈希算法四点要求,对用于加密的哈希算法来说,有两点格外重要。第一点是很难根据哈希值反向推导出原始数据,第二点是散列冲突的概率要很小。
