Registrations arrive typed in any case, sometimes with extra spaces at the ends. Given full_name containing exactly one first name and one last name separated by one or more spaces, return the badge text Last, First with each name capitalised (first letter uppercase, the rest lowercase).
Examples
Input: full_name = "ada lovelace"
Output: "Lovelace, Ada"
Input: full_name = " GRACE hopper "
Output: "Hopper, Grace"
Constraints
full_namecontains exactly two words made of letters, separated and possibly surrounded by spaces
Goals
- Split a full name into first and last parts
- Normalise capitalisation
- Format as `Last, First`
