我这边有个场景是针对数据去重，但又不是简单的去重，是有时间区间范围内的交集、并集计算。

废话不多说，我估计有不少人记不清集合的并集、差集、交集的概念了。

集合的分类:

并集：以属于A或属于B的元素为元素的集合成为A与B的并（集）
交集：以属于A且属于B的元素为元素的集合成为A与B的交（集）

差集：以属于A而不属于B的元素为元素的集合成为A与B的差 (集)

如果只是去重的化，完全可以使用golang map实现。比如下面的例子就可以实现去重。

         map 
         [ 
         string 
         ] 
         int 
         { 
        
         "baidu.com" 
         : 
          
         0 
         , 
        
"apple.com" 
          
         "google.com" 
           
         }

和我们预料的一样，必须出错！

golang-set是我在github找到的一个库，其实也没得选…. go get 安装go库包时候因为参数不对，总是失败….
