数组和切片使用技巧

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]
}
