一.阿里巴巴笔试题: public class T implements Cloneable { public static int k = 0; public static T t1 = new T("t1"); public static T t2 = new T("t2"); public static int i = print("i"); public static int n = 99; public int j = print(&q
在前面几篇博文中曾经提到链表(list).队列(queue)和(stack),为了更加系统化,这里统一介绍着三种数据结构及相应实现. 1)链表 首先回想一下基本的数据类型,当需要存储多个相同类型的数据时,优先使用数组.数组可以通过下标直接访问(即随机访问),正是由于这个优点,数组无法动态添加或删除其中的元素,而链表弥补了这种缺陷.首先看一下C风格的单链表节点声明: // single list node define typedef struct __ListNode { int val; st
std::queue template <class T, class Container = deque<T> > class queue; FIFO queue queues are a type of container adaptor, specifically designed to operate in a FIFO context (first-in first-out), where elements are inserted into one end of the
Suppose you have a random list of people standing in a queue. Each person is described by a pair of integers(h, k), where h is the height of the person and k is the number of people in front of this person who have a height greater than or equal to h
Implement the following operations of a queue using stacks. push(x) -- Push element x to the back of queue. pop() -- Removes the element from in front of queue. peek() -- Get the front element. empty() -- Return whether the queue is empty. Notes: You
看源码可以把python看得更透,更懂,想必也是开发人员的必经之路. 现在有个任务,写个线程池.使用Queue就能写一个最简单的,下面就来学学Queue源码. 源码之Queue: class Queue: """Create a queue object with a given maximum size. If maxsize , the queue size is infinite. 告诉你创建一个给出长度的队列,如果长度不大于0那么队列长度将变成无限. Queue构造方
