获取某个类型的字节数
package main
import (
"fmt"
"reflect"
)
func main() {
var t T
tType := reflect.TypeOf...(t)
n := tType.Size()
fmt.Println("A", tType, "object is", n, "bytes.")
}
type Person struct {
FirstName...footprint per value as Person.
type T Person
A main.T object is 24 bytes.
----
// T has (8 + 4) ==...Explain if original order is preserved.
list去重
package main
import "fmt"
func main() {
type T string...*int64
func main() {
var a, b, c, d int64 = 11, 22, 33, 11
x := []T{&b, &a, &b, &b, &c, &b, &a, &d
