Basic usage is just to import the library as the following example:

import (
	"log"

	"github.com/PacoDw/deviceNTask/dnt"
)

func main() {
	if err := dnt.CreateOptimalConfigurationFile("challenge.in"); err != nil {
		log.Fatal(err)
	}
}

If you want to run the current example, clone the repository and once you are in the folder project open the terminal and write the following command to run it:

$ go run main.go

And the challenge.out file will generate will the results

Note: you need the file challenge.in in order to work fine
