Instructions

Write a function ReverseSecondHalf() that takes a string as an argument and prints the second half reversed. If the length of the string is odd, round it up.

• Prints the second half reversed followed by newline \n.
• If the string is empty, return Invalid Output.
• If the string's length equals one, return it, followed by newline \n.

Expected function

func ReverseSecondHalf(str string) string {
}

Usage

Here is a possible program to test your function :

package main

import "fmt"

func main() {
    fmt.Print(ReverseSecondHalf("This is the 1st half This is the 2nd half"))
    fmt.Print(ReverseSecondHalf(""))
    fmt.Print(ReverseSecondHalf("Hello World"))
}

And its output :

$ go run . | cat -e
flah dn2 eht si sihT$
Invalid Output$
dlroW$
