Instructions

Write a function that takes a string as an argument and returns the letter G followed by a newline \n if the argument length is more or equal than 3, otherwise returns Invalid Input followed by a newline \n.

• If it's an empty string return G followed by a newline \n.

Expected function

func PrintIf(str string) string {

}

Usage

Here is a possible program to test your function:

package main

import (
	"fmt"
)

func main() {
	fmt.Print(PrintIf("abcdefz"))
	fmt.Print(PrintIf("abc"))
	fmt.Print(PrintIf(""))
	fmt.Print(PrintIf("14"))
}

And its output:

$ go run . | cat -e
G$
G$
G$
Invalid Input$
