## Boolean
### Instructions
Create a `.go` file and copy the code below into that file
and add the code necessary so the program works.
- The program must be submitted inside a folder with the name `boolean`.
```go
func printStr(str string) {
arrayStr := []rune(str)
for i := 0; i < len(arrayStr); i++ {
z01.PrintRune(arrayStr[i])
}
z01.PrintRune('\n')
}
func isEven(nbr int) boolean {
if even(nbr) == 1 {
return yes
} else {
return no
}
}
func main() {
if isEven(lengthOfArg) == 1 {
printStr(EvenMsg)
} else {
printStr(OddMsg)
}
}
```
### Expected output
```console
student@ubuntu:~/student/boolean$ go build
student@ubuntu:~/student/boolean$ ./boolean "not" "odd"
I have an even number of arguments
student@ubuntu:~/student/boolean$ ./boolean "not even"
I have an odd number of arguments
```
