Accounts Merge: coding question

Available question text

Given lists of accounts where each account has a name and emails, merge accounts that share any email by grouping connected emails (e.g., via union-find or graph traversal) and return each person's name with their sorted unique emails. Note names alone don't imply same person — connectivity is determined solely by shared email addresses.
