• A word is a sequence of characters delimited by spaces or by the start/end of the argument.

Expected Function

    // ...
}

Usage

Here is a possible way to test your function:

package main

import (
    "fmt"

    "piscine"
)

func main() {
    fmt.Print(piscine.FirstWord("hello there"))
    fmt.Print(piscine.FirstWord(""))
    fmt.Print(piscine.FirstWord("hello   .........  bye"))
}

And its output:

$ go run .
hello

hello
$
