In this LeetCode tutorial, we're diving deep into problem 966, Vowel Spellchecker. This problem presents a unique challenge where we must implement a spellchecker with a specific hierarchy of rules: exact match, case-insensitive match, and a custom vowel-error match. A naive brute-force approach is too slow, so we'll walk through the optimal solution using pre-computation. Learn how to leverage three different hash maps (a set and two dictionaries) to handle each rule efficiently, ensuring you respect the strict order of priority. We'll break down the Python code step-by-step and analyze the time and space complexity, making this a great lesson in using the right data structures for performance.
Perfect for coding interview preparation and improving problem-solving skills.
