Instructions

Write a function called RetainFirstHalf() that takes a string as an argument and returns the first half of this string.

• If the length of the string is odd, round it down.
• If the string is empty, return an empty string.
• If the string length is equal to one, return the string.

Expected function

func RetainFirstHalf(str string) string {

}

Usage

Here is a possible program to test your function:

package main

import (
	"fmt"
	"piscine"
)

func main() {
	fmt.Println(piscine.RetainFirstHalf("This is the 1st halfThis is the 2nd half"))
	fmt.Println(piscine.RetainFirstHalf("A"))
	fmt.Println(piscine.RetainFirstHalf(""))
	fmt.Println(piscine.RetainFirstHalf("Hello World"))
}

And its output:

$ go run . | cat -e
This is the 1st half$
A$
$
Hello$
