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"
)

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

And its output:

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