Count vowel words

CodingAlgorithms & data structuresEntry–Mid~10 min

Given a sentence of words separated by single spaces (possibly the empty string), count how many words begin with a vowel — one of 'a', 'e', 'i', 'o', 'u' — comparing case-insensitively. For example, 'An apple every day' has 3 such words ('An', 'apple', 'every').

vowel_start_count(s: str) → int
Examples

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.
