2. Navigate to the directory.
3. Create a file named whitespace.go with the following content:

        package main

        import (
          "fmt"

          "regexp"
          "strconv"

        func main() {

          stringToTrim := "\t\t\n Go \tis\t Awesome \t\t"
          trimResult := strings.TrimSpace(stringToTrim)
          fmt.Println(trimResult)

          stringWithSpaces := "\t\t\n Go \tis\n Awesome \t\t"
          r := regexp.MustCompile("\\s+")
          replace := r.ReplaceAllString(stringWithSpaces, " ")
          fmt.Println(replace)

          needSpace := "need space"
          fmt.Println(pad(needSpace, 14, "CENTER"))
