3.1Describe how you could use a single array to implement three stacks for stack 1, we will use [0, n/3)for stack 2, we will use [n/3, 2n/3)for stack 3, we will use [2n/3, n) ; ]; ] = {,,}; //栈顶指针,指向下一可以放元素的位置 bool isEmpty(int stackNum){ assert(stack…

Cracking the Coding Interview(Stacks and Queues) 1.Describe how you could use a single array to implement three stacks. 我的思路:一般堆栈的实现会利用一个数组,这里一个数组若实现3个堆栈,直接考虑把数组划分为3个部分,相当于3个独立的数组,所以就有以下的实现. 但是,这种实现方式的缺点在于均分了每个stack需要的space,但是事先无法确定每个stack是否需要更多的spac…

Algorithm | Coursera - by Robert Sedgewick Type the code one by one! 不要拜读--只写最有感触的!而不是仅仅做一个笔记摘录员,那样毫无意义! 动手实现.看懂不等于会写--用sublime 写,而非ide(强迫白板写代码)-- 默写代码 直接看ppt优先, 而不是被动看视频 不要拜读--没必要看废话 循循善诱--要是我大一时候看这本书就好了!但是现在开始也不算晚. 很多知识不用查,自己拿编译器print查看 时刻记得资源有限--这…

栈和队列 大型填坑现场,第一部分的还没写,以上. 栈和队列是很基础的数据结构,前者后进先出,后者先进先出,如下图: 下面开始将客户端和具体实现分开,这样有两个好处:一是客户端不知道实现的细节,但同时也会有很多不同实现来选择:二是实现方面也不知道客户端需求的细节,但同时很多客户端可以也重用一样的实现.接口就像把二者连接起来的桥梁. stacks 栈的操作主要是出栈入栈,热身来一个放字符串的栈. stack API 栈的测试代码 public static void main(String[] ar…
