#git subtree 的用法

假如有一个iOS的项目,我用到了很多外部的库,如AFNetworking,我怎么把它集成进来呢?

##通过submodule的方法

把这个项目追加到自己是项目中:

git submodule add [email protected]:AFNetworking/AFNetworking.git Vendor/AFNetworking

#Rails 国际化

从 rails 2.2开始就支持了 ruby 国际化的 gem. 提供了一个任意使用扩展的框架,用来翻译你的程序一个完整的自定义语言.不仅仅是英语. 给你的程序提供多语言支持.

通常国际化的过程就是把所有的字符串抽象出来.然后放在特定的地方,而本地化的过程就是提供对应的翻译和本地的格式. 所以,在 rails 程序里国际化的过程就是:

1. 确保支持 i18n
2. rails 哪里找到对应的本地字典
3. 告诉 rails 怎么设置和保护和切换地域.

#[codility]MinAvgTwoSlice


def solution(A):
    # write your code in Python 2.6

    # can not be smaller and also it can not be bigger, or the average of the 
    # whole slice will change
    # every slice can be divide into two kinds of subslices, e.g., two-element and three element
