The Go language USES map to implement the stack method

This article demonstrates an example of how the Go language USES map to implement stack functionality. Share with you for your reference. The specific implementation method is as follows:

package stack

import (

    "strconv"

)

type Stack struct {

    quenu map[int]int

}

func New() *Stack{

    s := new(Stack)

    s.quenu = make(map[int]int)

    return s

}

func (s *Stack) Push(i int) {

    s.quenu[len(s.quenu)] = i

}

func (s *Stack) Pop() {

    delete(s.quenu, len(s.quenu)-1)

}

func (s *Stack) String() string {

    info := ""

    for i := 0; i < len(s.quenu); i++ {

        info = info + "[" + strconv.Itoa(i) + "," + strconv.Itoa(s.quenu[i]) + "]"

    }

    return info

}

I hope this article has been helpful to your programming of Go language.
