我第一次见到Prolog这门独特的编程语言是在<七周七语言(Seven Languages in Seven Weeks)>中看到的.<七周七语言>名字看起来与市面上什么<三十天……从入门到精通>之类的垃圾书类似,但完全不是那回事.<七周七语言>的目标在于让读者了解到这些语言独有的编程思想和设计模式.而且它也不是什么入门书.Prolog是门声明式编程语言,它与我们平时最常遇到的命令式编程语言有很大的不同.命令式语言需要你精确地告诉计算机如何完成一项工作,而声…
[简介] 列表是Prolog编程中常用的一种重要的递归数据结构 列表是一个有限的元素序列 实例: 所有Prolog术语都可以是列表的元素,一个非空的List应该含有两个元素:头元素(Head)和尾元素(tail) 头是指List中的第一个元素,除去头都是尾 "列表的尾部也总是一个列表 / The tail of a list is always a list" 空List无头无尾 [操作:分割] Prolog有一个特殊的内置操作符|,它可以用来将列表分解为它的头部和尾部,|操作符是编写…
Suppose you are at a party with n people (labeled from 0 to n - 1) and among them, there may exist one celebrity. The definition of a celebrity is that all the other n - 1people know him/her but he/she does not know any of them. Now you want to find…
Follow up for "Find Minimum in Rotated Sorted Array":What if duplicates are allowed? Would this affect the run-time complexity? How and why? Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e., 0 1 2 4 5 6 7 might be…
Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2). Find the minimum element. You may assume no duplicate exists in the array. 这道寻找旋转有序数组的最小值肯定不能通过直接遍历整个数组来寻找,这个方法过于简单粗暴,这样的话,旋不…
