966. Vowel Spellchecker

Given a wordlist, we want to implement a spellchecker that converts a query word into a correct word. For a given query word, the spell checker handles two categories of spelling mistakes: Capitalization: If the query matches a word in the wordlist (case-insensitive), then the query word is returned with the same case as the case in the wordlist. Example: wordlist = ["yellow"], query = "YellOw": correct = "yellow" Example: wordlist = ["Yellow"], query = "yellow": correct = "Yellow" Example: wordlist = ["yellow"], query = "yellow": correct = "yellow" Vowel Errors: If after replacing the vowels ('a', 'e', 'i', 'o', 'u') of the query word with any vowel individually, it matches a word in the wordlist (case-insensitive), then the query word is returned with the same case as the match in the wordlist. Example: wordlist = ["YellOw"], query = "yollow": correct = "YellOw" Example: wordlist = ["YellOw"], query = "yeellow": correct = "" (no match) Example: wordlist = ["YellOw"], query = "yllw": correct = "" (no match) In addition, the spell checker operates under the following precedence rules: When the query exactly matches a word in the wordlist (case-sensitive), you should return the same word back. When the query matches a word up to capitlization, you should return the first such match in the wordlist. When the query matches a word up to vowel errors, you should return the first such match in the wordlist. If the query has no matches in the wordlist, you should return the empty string. Given some queries, return a list of words answer, where answer[i] is the correct word for query = queries[i].
/**
 * @param {string[]} wordlist
 * @param {string[]} queries
 * @return {string[]}
 */
var spellchecker = function(wordlist, queries) {
    // Helper function to normalize vowels in a word
    const normalizeVowels = (word) => {
        return word.toLowerCase().replace(/[aeiou]/g, '*');
    };

    // Step 1: Build lookup structures
    const exactWords = new Set(wordlist); // For exact match
    const caseInsensitiveMap = new Map(); // For case-insensitive match
    const vowelErrorMap = new

3541. Find Most Frequent Vowel and Consonant

You are given a string s consisting of lowercase English letters ('a' to 'z'). Your task is to: Find the vowel (one of 'a', 'e', 'i', 'o', or 'u') with the maximum frequency. Find the consonant (all other letters excluding vowels) with the maximum frequency. Return the sum of the two frequencies. Note: If multiple vowels or consonants have the same maximum frequency, you may choose any one of them. If there are no vowels or no consonants in the string, consider their frequency as 0. The frequency of a letter x is the number of times it occurs in the string.
/**
 * @param {string} s
 * @return {number}
 */
var maxFreqSum = function(s) {
    // Step 1: Define vowels for easy lookup
    const vowels = new Set(['a', 'e', 'i', 'o', 'u']);

    // Step 2: Create frequency maps for vowels and consonants
    const vowelFreq = {};
    const consonantFreq = {};

    // Step 3: Loop through each character in the string
    for (let char of s) {
        if (vowels.has(char)) {
            // It's a vowel
            vowelFreq[char] = (vowelFreq[char] || 0) + 1

3227. Vowels Game in a String

Alice and Bob are playing a game on a string. You are given a string s, Alice and Bob will take turns playing the following game where Alice starts first: On Alice's turn, she has to remove any non-empty substring from s that contains an odd number of vowels. On Bob's turn, he has to remove any non-empty substring from s that contains an even number of vowels. The first player who cannot make a move on their turn loses the game. We assume that both Alice and Bob play optimally. Return true if Alice wins the game, and false otherwise. The English vowels are: a, e, i, o, and u.
/**
 * @param {string} s
 * @return {boolean}
 */
var doesAliceWin = function(s) {
    // Define a set containing all lowercase English vowels
    const vowels = new Set(['a', 'e', 'i', 'o', 'u']);
    let prefixParity = new Set();
    // Initialize a counter to track the number of vowels in the string
    let count = 0;

    // Add initial parity (empty prefix)
    prefixParity.add(0);

    // Loop through each character in the string
    for (let char of s) {
        // If the character is a v

Renewing Let's Encrypt Certificates 


# Renewing Let's Encrypt Certificates with Certbot

This guide explains how to list, delete, renew, and verify Let's Encrypt certificates on an OpenWISP setup using **Certbot** and the **webroot authenticator**.

---

## 1. List Existing Certificates

To check which certificates are currently installed:

```bash
