go 循环切片得到重复移除成别名

import "fmt"
func removeDuplicateElement(addrs []string) []string {
   result := make([]string, 0, len(addrs))
   temp := map[string]struct{}{}
   idx := 0
for _, item := range addrs {
      if _, ok := temp[item]; !ok {
         temp[item] = struct{}{}
         result = append(result, item)
      } else {
         idx++
         item += fmt.Sprintf("(%v)", idx)
         result = append(result, item)
      }
   }
   return result
}


func main() {
   fmt.Println(removeDuplicateElement([]string{"fsdf","fdsfsdf","fsdf"}))



}



[fsdf fdsfsdf fsdf(1)]
