1.概述 所谓依赖倒置原则(Dependence Inversion Principle)就是要依赖于抽象,不要依赖于具体.简单的说就是要求对抽象进行编程,不要对实现进行编程,这样就降低了客户与实现模块间的耦合,并由此引申出IoC.DI以及Ioc容器等概念. 2.意图 面向过程的开发,上层调用下层,上层依赖于下层,当下层剧烈变动时上层也要跟着变动,这就会导致模块的复用性降低而且大大提高了开发的成本.   面向对象的开发很好的解决了这个问题,一般情况下抽象的变化概率很小,让用户程序依赖于抽象,实现…

刷题备忘录,for bug-free 招行面试题--求无序数组最长连续序列的长度,这里连续指的是值连续--间隔为1,并不是数值的位置连续 问题: 给出一个未排序的整数数组,找出最长的连续元素序列的长度. 如: 给出[100, 4, 200, 1, 3, 2], 最长的连续元素序列是[1, 2, 3, 4].返回它的长度:4. 你的算法必须有O(n)的时间复杂度 . 解法: 初始思路 要找连续的元素,第一反应一般是先把数组排序.但悲剧的是题目中明确要求了O(n)的时间复杂度,要做一次排序,是不能达…

handlebars相对来讲算一个轻量级.高性能的模板引擎,因其简单.直观.不污染HTML的特性,我个人特别喜欢.另一方面,handlebars作为一个logicless的模板,不支持特别复杂的表达式.语句,只内置了一些基本的语法,像if.each这些.可惜的是就连if都十分弱,只能判断值是否为true/false,或转化后是否为true/false,不能对值进行比较.不过,handlebars提供了自定义helper的能力,通过自定义helper,可以实现非常丰富的功能.本篇来总结一下hand…
