package main

import (
    . "../../queue"
    . "fmt"
    )

func main()  {
    q := Queue{1,2,3,4}
    q.Push(5)
    q.Pop()
    q.Pop()
    q.Pop()
    Println(q.IsEmpty())
}

Go語言中可以通過type關鍵字宣告型別，如type StrSlice []string 將[]string（string型別的切片）宣告為StrSlice 型別

package queue

type Queue []int

func (q *Queue)  Push(v int) {
    *q = append(*q, v)
}

func (q *Queue)  Pop() int {
    head := (*q)[0]
    *q = (*q)[1:]
    return head
}

func (q *Queue) IsEmpty() bool {
    return len(*q) == 0

}
