wordflip

Instructions

Write a function WordFlip() that takes a string as input and returns it in reverse order.

  • The output should be followed by a newline \n.
  • If the string is empty, return Invalid Output.
  • Ignore multiple spaces between words and trim any leading or trailing spaces in the string.

Expected function

func WordFlip(str string) string {

}

Usage

Here is a possible program to test your function:

package main

import (
	"fmt"
)

func main() {
	fmt.Print(WordFlip("First second last"))
	fmt.Print(WordFlip(""))
	fmt.Print(WordFlip("     "))
	fmt.Print(WordFlip(" hello  all  of  you! "))
}

And its output:

$ go run . | cat -e
last second First$
Invalid Output$
$
you! of all hello$
