Swift 提示:Initialization of variable was never used consider replacing with assignment to _ or removing it 的原因: var //代表变量,变量的值可以改变 let//代表常量类型不可改变 var ceshi:Double = 10//假如声明的变量没有改变的话Swift也会提示将其改为let,而且在下面的代码中没有用到该变量Swift就会提示将let改为下划线,因为下划线代表忽略该变量,就相

The Problem. 求解8数码问题.用最少的移动次数能使8数码还原. Best-first search.使用A*算法来解决,我们定义一个Seach Node,它是当前搜索局面的一种状态,记录了从初始到达当前状态的移动次数和上一个状态.初始化时候,当前状态移动次数为0,上一个状态为null,将其放入优先级队列,通过不断的从优先级队列中取出Seach Node去扩展下一级的状态,直到找到目标状态.对于优先级队列中优先级的定义我们可以采用:Hamming priority function 和
实现一个泛型的双端队列和随机化队列,用数组和链表的方式实现基本数据结构,主要介绍了泛型和迭代器. Dequeue. 实现一个双端队列,它是栈和队列的升级版,支持首尾两端的插入和删除.Deque的API如下 public class Deque<Item> implements Iterable<Item> { public Deque() // construct an empty deque public boolean isEmpty() // is the deque emp

Initialization happens when a variable is given a value at the moment it is created. Assignment obliterates the variable's current value and replace the value with a new one.
