golang 之 stack (基于 slice 实现的简单 arrarylist)

由于在 golang 中没有方便的 interface 转 string 使用了
"github.com/spf13/cast" 包

   type Stack struct {

    arraryList.ArraryList
    }
    
    func main() {
    
    stack := InitNoParam()
    for i := 0; i < 10; i++ {
    	stack.Push(i)
    }
    
    stack.Pop()
    fmt.Println(stack.ToString())
    
    }
    
    func InitNoParam() *Stack {
    return &Stack{arraryList.ArraryList{Slice: make([]interface{}, 0)}}
    }
    
    func Init(cap int) *Stack {
    return &Stack{arraryList.ArraryList{Slice: make([]interface{}, 0, cap)}}
    }
    
    func (this *Stack) Push(elem interface{}) {
    this.ArraryList.AddLast(&this.Slice, elem)
    }
    
    func (this *Stack) Pop() {
    this.Slice = this.Remove(this.Slice, len(this.Slice)-1)
    }
    
    func (this *Stack) Peek() (interface{}) {
    return this.GetLast(this.Slice)
    }
    
    func (this *Stack) GetSize() (int) {
    return len(this.Slice)
    }
    
    func (this *Stack) IsEmpty() (bool) {
    if len(this.Slice) == 0 {
    	return true
    }
    return false
    }
    
    func (this *Stack) ToString() string {
    s := "["
    for index, sl := range this.Slice {
    
    	if index == len(this.Slice)-1 {
    		s += cast.ToString(sl)+"] top"
    	} else {
    		s += cast.ToString(sl) + ","
    	}
    }
    return s
    }
    
    func (this *Stack) GetCapacity() (interface{}) {
    return cap(this.Slice)
    }
