### Instructions
|
||
|
|
|
||
|
|
Write a function that takes a pascal case string and returns the same string with spaces between each word.
|
||
|
|
|
||
|
|
- The function must return an empty string if the input string is empty.
|
||
|
|
|
||
|
|
- The function must return `"Error"` if the input string is not a pascal case string.
|
||
|
|
|
||
|
|
- The pascal case begins with a capital letter, and each word begins with a capital letter without a space between them for example: `"HelloWorld`"` is a valid pascal case string.
|
||
|
|
|
||
|
|
- The pascal case cannot contain any non-alphabetic character, for example: `"Hello World12`"` is not a valid pascal case string.
|
||
|
|
|
||
|
|
### Expected function
|
||
|
|
|
||
|
|
```go
|
||
|
|
func SetSpace(s string) string {
|
||
|
|
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a possible program to test your function :
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import "fmt"
|
||
|
|
|
||
|
|
func main(){
|
||
|
|
fmt.Println(SetSpace("HelloWorld"))
|
||
|
|
fmt.Println(SetSpace("Hello World12"))
|
||
|
|
fmt.Println(SetSpace("Hello World"))
|
||
|
|
fmt.Println(SetSpace("LoremIpSumWord"))
|
||
|
|
fmt.Println(SetSpace(""))
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output :
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ go run . | cat -e
|
||
|
|
Hello World$
|
||
|
|
Error$
|
||
|
|
Error$
|
||
|
|
Lorem Ipsum Word$
|
||
|
|
$
|
||
|
|
```
