Write a function space_greeting() that interacts with the user via input(). It should:
- Prompt for a name.
- Prompt for two integers (one after the other).
- Return a single string formatted as:
Hello <name>! The sum of your numbers is <sum>
The sum must be numeric addition, not string concatenation. Example:
- Input: "Ada", "4", "5" → Return: "Hello Ada! The sum of your numbers is 9".
- Input: "", "0", "0" → Return: "Hello ! The sum of your numbers is 0".
