Implement a stack structure with pop, append, and print top functionalities.

Solution

You can implement a stack using a slice object.

package main

import "fmt"

func main() {

// Create

var stack []string

Run

First, we use the built-in append() function to implement the append behavior. Then we use len(stack)-1 to select the top of the stack and print.

For pop, we set the new length of the stack to the position of the printed top value, len(stack)-1.
