数组和切片使用技巧

两个切片如何去重

func sliceUniq(lenSlice, shortSlice []string) (process []string) {
   lenMap := make(map[string]bool, len(lenSlice))
   shortMap := make(map[string]bool, len(shortSlice))
   for _, v := range lenSlice { // []string{"A", "b", "c", "d"}
      lenMap[v] = false
   }
   for _, v := range shortSlice { // []string{"c", "b"}
      shortMap[v] = false
   }
   for k, _ := range shortMap {
      if _, ok := lenMap[k]; ok {
         delete(lenMap, k)
      }
   }
   for k, _ := range lenMap {
      process = append(process, k)
   }
   return
}

func main() {
  res:=sliceUniq([]string{"A", "b", "c", "d"}, []string{"c", "b"})
	fmt.Println(res)
	// [d A]
}
