题目：

Consider a special type of animal known as an Ewwok that reproduces following the rules below:
An Ewwok dies six months after it is born. That is, if an Ewwok is born in month 0, it will die in month 6.
An Ewwok gives birth to two Ewwoks every two months until it dies. That is, if an Ewwok is born in month 0, it will reproduce in months 2 and 4. It does not reproduce in month 6 or beyond.
In each month, among all the Ewwoks that have been alive for exactly three months, there is one that dies. That is, if there are n (n > 0) Ewwoks that are born in month 0, one of them will die in month 3.
Given an integer initial representing the number of Ewwoks born in month 0, and an integer m representing a month, your task in this question is to write a program that calculates and returns the number of Ewwoks alive in month m.

扩展Nginx的WebDav支持

1、简介

　　废话可不看~

　　WebDAV （Web-based Distributed Authoring and Versioning） 一种基于 HTTP 1.1协议的通信协议。它扩展了HTTP 1.1，在GET、POST、HEAD等几个HTTP标准方法以外添加了一些新的方法，使应用程序可对Web Server直接读写，并支持写文件锁定(Locking)及解锁(Unlock)，还可以支持文件的版本控制。

　　Nginx的轻量高效十分合我的胃口，但Nginx默认只实现了WebDAV的PUT、DELETE、MKCOL、COPY、MOVE，这显然不能满足日常的使用。所以，这里使用Nginx加载动态模块 nginx-dav-ext-module 来支持WebDAV额外需要的PROPFIND和OPTIONS方法。
