setspace

Instructions

Write a function that takes a PascalCase string and returns the same string with a space between each word.

• The function must return an empty string if the input is an empty string.

• The function must return "Error" if the input string is not a PascalCase string.

• The PascalCase begins with a capital letter, and each word begins with a capital letter without a space between them, for example: "HelloWorld" is a valid PascalCase string.

• The PascalCase cannot contain any non-alphabetic character, for example: "Hello World12" is not a valid PascalCase string.

Expected function

func SetSpace(s string) string {

}

Usage

Here is a possible program to test your function:

package main

import (
	"fmt"
)

func main() {
	fmt.Println(SetSpace("HelloWorld"))
	fmt.Println(SetSpace("HelloWorld12"))
	fmt.Println(SetSpace("Hello World"))
	fmt.Println(SetSpace(""))
	fmt.Println(SetSpace("LoremIpsumWord"))
}

And its output:

$ go run . | cat -e
Hello World$
Error$
Error$
$
Lorem Ipsum Word$
$
