Instructions

Write a function ThirdTimeIsACharm() that takes a string as an argument and returns another string with every third character.

• Return the output followed by a newline \n.
• If the string is empty, return a newline \n.
• If there is no third character, return a newline \n.

Expected function

func ThirdTimeIsACharm(str string) string {

}

Usage

Here is a possible program to test your function:

package main

import (
	"fmt"
	"piscine"
)

func main() {
	fmt.Print(piscine.ThirdTimeIsACharm("123456789"))
	fmt.Print(piscine.ThirdTimeIsACharm(""))
	fmt.Print(piscine.ThirdTimeIsACharm("a b c d e f"))
	fmt.Print(piscine.ThirdTimeIsACharm("12"))
}

And its output:

$ go run . | cat -e
369$
$
b e$
$
