Question

A support dashboard estimates how varied a ticket's wording is. Given the ticket text — words separated by single spaces, possibly empty — return the number of distinct words when compared case-insensitively. For example, 'The printer THE PRINTER again' has 3 distinct words: 'the', 'printer', and 'again'.

Implement
count_unique_words(ticket: str) → int
Examples
in["The printer THE PRINTER again"]out3
What a strong answer looks like

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.

Vibe coding: describe the solution in plain language (or narrate it) and the coach grades your approach. Generating runnable code from your description is coming next.

Run or narrate your approach, then ask the coach.
