Below code:

// You can edit this code!
// Click here and start typing.
package main

import "fmt"

type A []*B
type B struct {
    I int
}

func main() {
    x := A{
        &B{1}, &B{2},
    }
    fmt.Println(x.I)
}

gives error: x.I undefined (type A has no field or method I)

1. Is the composite literal syntax correct? to initialize value of type A

2. How to access field I from variable x?
