join

Instructions

Write a function that simulates the behaviour of the Join function in Go. This function returns the concatenation of all the strings of a slice of strings separated by a separator passed in argument.

Expected function

func Join(strs []string, sep string) string {

}

Usage

Here is a possible program to test your function :

package main

import (
	"fmt"
	"piscine"
)

func main() {
	toConcat := []string{"Hello!", " How", " are", " you?"}
	fmt.Println(piscine.Join(toConcat, ":"))
}

And its output :

$ go run .
Hello!: How: are: you?
$
