Are you afraid of me? (你们怕我吗?) Don't be.(不用怕) I am a programmer who just won't die.(我是不会死的程序员) 自从跟踪到32位CPU的逻辑地址等同于线性地址,不仅在Windows中,还有在Linux(Android)中,你所看到的.所想到的一切,都不是事实 —— 认识到了这一个层次,编程序的所有神秘感消失了. 以前,程序运行中崩溃是天大的事 —— 如今,在这神秘感消失之后,只要跟踪堆栈地址即可迎刃而解,因为逻辑地址等…

int p; int *p; int p[3]; int *p[3];分析方式:首先从P开始分析,先与[]结合因为其优先级比*高,所以p是一个数组,然后再与*结合,说明数组里的元素是指针类型,然后再与int结合,说明指针所指向的内容的类型是整形的,所以P是一个由返回整形数据的指针所组成的数组. int (*p)[3];分析:1:p是一个指针,指针所指向的内容是一个数组,数组里的元素是整形,P是一个指向由整形数据组成的数组的指针. int **p:P是一个指针,然后指针所指向的元素是一个指针,说明…

链接:传送门 题意:判断 m 组数,如果某一组中出现负数就判断这一组中是否存在与之相反的数,如果每一组中都满足要求则输出 "NO" 反之输出 "YES" 思路:对于任意的一组数,if v[i] < 0 则 vector.find( v.begin() , v.end() , -v[i] )查一下在这组数中是否出现过相反数,如果 find != v.end() 说明出现过,返回 true 否则返回一个 false /***********************…

Python NLTK 获取文本语料和词汇资源 作者:白宁超 2016年11月7日13:15:24 摘要:NLTK是由宾夕法尼亚大学计算机和信息科学使用python语言实现的一种自然语言工具包,其收集的大量公开数据集.模型上提供了全面.易用的接口,涵盖了分词.词性标注(Part-Of-Speech tag, POS-tag).命名实体识别(Named Entity Recognition, NER).句法分析(Syntactic Parse)等各项 NLP 领域的功能.本文主要介绍NLTK(Na…

Help Hanzo 题意:求a~b间素数个数(1 ≤ a ≤ b < 231, b - a ≤ 100000).     (全题在文末) 题解: a~b枚举必定TLE,普通打表MLE,真是头疼.. b - a ≤ 100000 是关键. 类似素数筛的方法: 1.初始化vis[]=0 ; 2.素数的倍数vis[]=1; 3.  b较小时,素数筛解决   b很大时,素数筛的vis[]会MLE,此时用vis2[i-a]保存vis[i]就不会MLE 了.. #include<iostream>…

我在Erlang Resources 豆瓣小站上发起了一个征集活动 [链接] ,"[征集] 我们读过的Erlang论文",希望大家来参加.发起这样一个活动的目的是因为Erlang相关的出版物很少,很多时候都是从学术论文中寻找答案,而发现合适的论文是第一步,这个活动就是为了解决这个问题. 在一个极小的知识点可能都会有一篇精彩的论文为你条分缕析,抽丝剥茧,甚至可以拼凑起来一个完整的Erlang知识系统,我们开始吧... <面向软件错误构建可靠的分布式系统> Making rel…
