slice的增删改查:
//删除
func remove(slice []interface{}, i int) []interface{} {
// copy(slice[i:], slice[i+1:])
// return slice[:len(slice)-1]
return append(slice[:i], slice[i+:]...)
} //新增
func add(slice []interface{}, value interface{}) []interface{} {
return append(slice, value)
} //插入
func insert(slice *[]interface{}, index int, value interface{}) {
rear := append([]interface{}{}, (*slice)[index:]...)
*slice = append(append((*slice)[:index], value), rear...)
} //修改
func update(slice []interface{}, index int, value interface{}) {
slice[index] = value
} //查找
func find(slice []interface{}, index int) interface{} {
return slice[index]
} //清空slice
func empty(slice *[]interface{}) {
// *slice = nil
*slice = append([]interface{}{})
} //遍历
func list(slice []interface{}) {
for _, v := range slice {
fmt.Printf("%d ", v)
}
}
