创建一张表test_explode，表结构如下 表数据如下： 1.使用explode函数 select explode(friends) as friend from test_explode; 但是只使用explode函数很难满足实际需求，原因如下： 1.1 No other expressions are allowed in SELECT 0: jdbc:hive2://master01.hadoop.mob
从事web开发工作有一小段时间，REST风格的接口，这样的词汇总是出现在耳边，然后又没有完全的理解，您是不是有和我相同的疑问呢？那我们一起来一探究竟吧！ 就是用URL定位资源，用HTTP描述操作。 知乎大神Ivony有句话说的好： URL定位资源，用HTTP动词（GET,POST,DELETE,DETC）描述操作。 咱们不解释RES

There are N students in a class. Some of them are friends, while some are not. Their friendship is transitive in nature. For example, if A is a direct friend of B, and B is a direct friend of C, then A is an indirect friend of C. And we defined a frien
URL定位资源，用HTTP动词（GET,POST,DELETE,DETC）描述操作。 在设计web接口的时候，REST主要是用于定义接口名，接口名一般是用名次写，不用动词，那怎么表达“获取”或者“删除”或者“更新”这样的操作呢——用请求类型来区分。 比如，我们有一个friends接口，对于“朋友”我们有增删改查四种操作，

再起步 前面已经用了两个篇幅取描述复合类型，已经把复合类型的基本概念和重要知识点以及元组、列表都描述的很清楚了，核心基本都已经掌握。就还剩下字典和集合，本章就讲讲这两个玩意。 话不多说，直接上菜。我认为字典就类似于南方人中的青菜，虽然吃的不多，但是每顿都不可缺少。字典在

一、向函数中传递任意数量的实参 有时候，你预先不知道函数需要接受多少个实参，Python中函数可以收集任意数量的实参。 栗子：来看一个打印好友列表功能的函数，它需要接收任意数量的好友名。如下： 1 def print_friends(*friends):2 """打印好友名"""3 print(friends)4 5 prin

一、思想 通俗的说就是将所有关系的都连接起来，比方说A和B是朋友，B和C是朋友，那么A和C也是朋友，就算是中间隔着100个朋友这样的也算是朋友。 具体实现： 通过两个函数实现。 一是查找父节点函数，此函数可以使用递归调用来压缩路径。 二是合并函数，将两个没有连接的点连接起来。 二、例题 HD
