项目中的有趣题目 -- 吃饺子问题

题目描述: 近日,项目中偶遇一个有趣的题目,感慨多多,备忘之.抽象出来,大致是: 桌上一共有100个饺子,其中有10个饺子包了硬币,问:连续吃到硬币的期望次数是多少次? 首先,定义一下这里的连续,如果我们将吃饺子的顺序抽象为一个100位的二进制数.并且吃到饺子表示为1,没吃到则为0,那么: 如果一次和第二次吃到,那么可表示为: 110.....,那么这里的连续吃到的次数为1. 如果数字为: ...1111.... ,那么这里连续的4个1表示3次连续,也就是说只要连续,就算1次. 期望次数,也就是

Vue 实际项目中你可能会遇见的坑

纸上得来终觉浅,绝知此事要躬行! Vue的文档和教程看的太多,小的demo做的多,也不如自己实际的进行一个完整项目的开发.只有做了才知道原来问题这么多,这里列举了一些你做demo教程可能不会遇见的坑. 一.项目的登录拦截及用户权限访问控制问题. 一个很常见的需求就是对未登录的用户进行路由拦截和用户的权限访问,如果你的项目之前是通过后台控制访问路由的,那么之前的后端现在可能需要在前端也需要控制了,由于我们用vue脚手架搭建的都是纯前端的路由访问,先看看我们的一般的项目路径: 你可能会注意到Vue的

160504项目中的error

在学习时,曾经遇到将同组的项目导入时出现红叉的情况.但是没有发现具体错误.开始以为是build path 的问题,于是在Libraries中将相关Jar包重新检查并添加了一遍,但并没有解决问题.后来仔细检查后才发现,是一个很简单的问题,之前都想复杂了.JDK版本不一样,把JDK7换掉重新装JDK8,再把相关配置好,红叉就解决大半. 作为菜鸟程序员,有时候一个很小的问题就能造成很大影响.而经验不足时,更不知道从何入手.为了能顺利编写项目,更为了能在编写项目时能解决出现的问题和错误而不是不知所措,就

项目中选择css框架的苦恼

优点 a) 提高开发效率. b) 规范名称定义,便于维护. c) 规范项目开发流程 d)css代码更清晰.简单.html代码更合理. e) 大规模项目中可以减少用户下载弊端 a) 学习成本提高.你需要了解整个框架,需要阅读框架的文档. b)css框架对于一个小项目等页面来说很臃肿.框架中可能有大部分你用不到的代码. c)可能会无法帮助你的技术提高.太依赖框架,以至于很难排除bug.包括框架中本身就带的bug. d) 选择自己需要的框架与开发框架都很痛苦.写到后面发现越来越不灵活,越来越臃肿.
