不一定是最高效的办法：
```go
package main

import "fmt"

var (
di = []int{0, 1, 2}
dj = []int{0, 1}
dk = []int{0, 1, 2, 3, 4}
)

func main() {
res := getResult(di, dj, dk)
for _, item := range res {
fmt.Println(item)
}
}

func getResult(d0 []int, d1 ...[]int) (res [][]int) {
if len(d1) == 0 {
res = make([][]int, 0, len(d0))
for _, d := range d0 {
res = append(res, []int{d})
}
return
}
sub := getResult(d1[0], d1[1:]...)
for _, item := range d0 {
for _, s := range sub {
c := []int{item}
c = append(c, s...)
res = append(res, c)
}
}
return
}
```
