1、内盟古是省级区划，不是城市。
2、算法也很简单：
a）定位
b）用定位点左边的像素替换定位点的像素
d）定位点 = 定位点 + 1
e）重复 b ，直至定位点的像素 == 初始定位点左边的像素

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
