package main

import (
	"fmt"

	boa "github.com/davidn5013/snickerboa"
)

func main() {
	boa.OneArgChkOrExit("Missing argument")
	n := boa.Arg1ToIntOrExit()
	fmt.Println(boa.SumofPrimesUntil(n))
}

/*
 * Usage Exampel
 */

func main() {
	s := snickerboa.NewStack()
	fmt.Println(s.IsEmpty()) // true
	s.Push(1)
	s.Push(2)
	s.Push(3)
	fmt.Println(s.Size()) // 3
	item, err := s.Peek()
	if err != nil {
		fmt.Println(err)
	} else {
		fmt.Println(item) // 3
	}
	item, err = s.Pop()
	if err != nil {
		fmt.Println(err)
	} else {
		fmt.Println(item) // 3
	}
	fmt.Println(s.Size())    // 2
    fmt.Println(s.IsEmpty()) // false
}
