## wordflip |
||||||
|
|
||||||
|
### Instructions |
||||||
|
|
||||||
|
Write a function `WordFlip()` that receives a `string` and returns it in reverse order. |
||||||
|
|
||||||
|
- Prints the Output followed by newline `\n`. |
||||||
|
- If the string is empty, return `Invalid Output`. |
||||||
|
- Ignore spaces if there are more than one space in between words and ignore all spaces at the edge of the `string`. |
||||||
|
|
||||||
|
### Expected function |
||||||
|
|
||||||
|
```go |
||||||
|
func WordFlip(str string) string { |
||||||
|
|
||||||
|
} |
||||||
|
``` |
||||||
|
|
||||||
|
### Usage |
||||||
|
|
||||||
|
Here is a possible program to test your function: |
||||||
|
|
||||||
|
```go |
||||||
|
package main |
||||||
|
|
||||||
|
import ( |
||||||
|
"fmt" |
||||||
|
"piscine" |
||||||
|
) |
||||||
|
|
||||||
|
func main() { |
||||||
|
fmt.Print(piscine.WordFlip("First second last")) |
||||||
|
fmt.Print(piscine.WordFlip("")) |
||||||
|
fmt.Print(piscine.WordFlip(" ")) |
||||||
|
fmt.Print(piscine.WordFlip(" hello all of you! ")) |
||||||
|
} |
||||||
|
``` |
||||||
|
|
||||||
|
And its output: |
||||||
|
|
||||||
|
```console |
||||||
|
$ go run . | cat -e |
||||||
|
last second First$ |
||||||
|
Invalid Output$ |
||||||
|
$ |
||||||
|
you! of all hello$ |
||||||
|
``` |
