1291. Sequential Digits

An integer has sequential digits if and only if each digit in the number is one more than the previous digit. Return a sorted list of all the integers in the range [low, high] inclusive that have sequential digits.
/**
 * @param {number} low
 * @param {number} high
 * @return {number[]}
 */
var sequentialDigits = function(low, high) {
    // All sequential-digit numbers come from this string.
    // Every valid number is a substring of "123456789".
    const digits = "123456789";

    // This will store all sequential-digit numbers within [low, high].
    const result = [];

    // Sequential numbers can have lengths from 2 digits up to 9 digits
    for (let len = 2; len <= 9; len++) {

3534. Path Existence Queries in a Graph II

You are given an integer n representing the number of nodes in a graph, labeled from 0 to n - 1. You are also given an integer array nums of length n and an integer maxDiff. An undirected edge exists between nodes i and j if the absolute difference between nums[i] and nums[j] is at most maxDiff (i.e., |nums[i] - nums[j]| <= maxDiff). You are also given a 2D integer array queries. For each queries[i] = [ui, vi], find the minimum distance between nodes ui and vi. If no path exists between the two nodes, return -1 for that query. Return an array answer, where answer[i] is the result of the ith query. Note: The edges between the nodes are unweighted.
/**
 * @param {number} n
 * @param {number[]} nums
 * @param {number} maxDiff
 * @param {number[][]} queries
 * @return {number[]}
 */
var pathExistenceQueries = function (n, nums, maxDiff, queries) {
    // Pair: [value, index]
    const pairs = Array.from({ length: n }, (_, i) => [nums[i], i]);
    pairs.sort((a, b) => a[0] - b[0]);

程式碼審核

請你對目前這個 repository 進行「全面程式碼審查」。

重要限制:
1. 先不要直接修改任何程式碼。
2. 不要只做表面掃描,請先理解專案架構、執行流程、驗證機制、資料存取、部署方式後再提出問題。
3. 所有發現都必須指出:
   - 嚴重程度:Critical / High / Medium / Low
   - 問題類型:安全性 / 架構 / 錯誤處理 / 效能 / 可維護性 / 測試不足 / 部署風險
   - 影響範圍
   - 相關檔案與程式碼位置
   - 為什麼這是問題
   - 建議修正方式
   - 是否需要補測試
4. 不要提出沒有依據的猜測;如果無法確認,請標註「需人工確認」。
5. 優先找出會造成資安風險、生產環境錯誤、資料不一致、權限繞過、Token / Cookie / CORS / CSRF 問題、例外未處理、日誌外洩、弱掃風險的問題。
6. 請依照實際程式碼內容審查,不要只給一般建議。

請依照以下順序執行:

第一階段:專案盤點

Lighthouse MCP

請使用 lighthouse MCP 對以下登入頁執行行動裝置 Performance 稽核:

<Url>

請執行下列工作:

1. 記錄 Performance 分數、FCP、LCP、TBT、CLS 和 Speed Index。
2. 找出造成 LCP 超過 2.5 秒的主要原因。
3. 檢查 ASP.NET Core 10、Razor View、Razor Layout、CSS、JavaScript、圖片、Web Font、靜態資源、中介軟體及第三方資源。
4. 檢查靜態檔案壓縮、快取標頭、Response Compression、資源載入順序,以及是否存在 Render-blocking resources。
5. 依改善效益、修改風險與實作成本排序改善項目。
6. 修改程式碼時不得改變登入流程、驗證邏輯、頁面功能及既有 UI 行為。
7. 修改後再次使用 lighthouse MCP 執行相同條件的測試。
8. 比較修改前後的 Lighthouse 結果。
9. LCP 目標為 2.5 秒以下。

審核新舊程式碼

請只審查 `sha_old..sha_new` 範圍內的變更,不要修改任何檔案。

請以以下 Git 範圍為審查依據:

```bash
git log --oneline sha_old..sha_new
git diff --stat sha_old..sha_new
git diff sha_old..sha_new
```

審查範圍只限於 `sha_old` 之後到 `sha_new` 為止的變更。

可以閱讀其他未變更檔案作為上下文,但不要把原本就存在的舊問題列為本次問題,除非該問題是由 `sha_old..sha_new` 範圍內的變更引入、擴大或暴露。

本專案是 Flutter 專案,請特別審查:

* Widget lifecycle,例如 `initState`、`dispose`、Controller / Listener / Worker 是否釋放
* GetX 狀態管理是否有狀態殘留、重複刷新、Controller 過肥問題
* async / await 是否有 race condition、重複請求、頁面離開後仍更新狀

3532. Path Existence Queries in a Graph I

You are given an integer n representing the number of nodes in a graph, labeled from 0 to n - 1. You are also given an integer array nums of length n sorted in non-decreasing order, and an integer maxDiff. An undirected edge exists between nodes i and j if the absolute difference between nums[i] and nums[j] is at most maxDiff (i.e., |nums[i] - nums[j]| <= maxDiff). You are also given a 2D integer array queries. For each queries[i] = [ui, vi], determine whether there exists a path between nodes ui and vi. Return a boolean array answer, where answer[i] is true if there exists a path between ui and vi in the ith query and false otherwise.
/**
 * @param {number} n
 * @param {number[]} nums
 * @param {number} maxDiff
 * @param {number[][]} queries
 * @return {boolean[]}
 */
var pathExistenceQueries = function(n, nums, maxDiff, queries) {
    const comp = new Array(n).fill(0);

    // Build connected components
    for (let i = 1; i < n; i++) {
        if (nums[i] - nums[i - 1] <= maxDiff) {
            comp[i] = comp[i - 1];
        } else {
            comp[i] = comp[i - 1] + 1;

    }

3756. Concatenate Non-Zero Digits and Multiply by Sum II

You are given a string s of length m consisting of digits. You are also given a 2D integer array queries, where queries[i] = [li, ri]. For each queries[i], extract the substring s[li..ri]. Then, perform the following: Form a new integer x by concatenating all the non-zero digits from the substring in their original order. If there are no non-zero digits, x = 0. Let sum be the sum of digits in x. The answer is x * sum. Return an array of integers answer where answer[i] is the answer to the ith query. Since the answers may be very large, return them modulo 109 + 7.
/**
 * @param {string} s
 * @param {number[][]} queries
 * @return {number[]}
 */
var sumAndMultiply = function(s, queries) {
    const MOD = 1000000007;
    const MODB = BigInt(MOD);

    // Safe modular multiplication using BigInt
    const mulmod = (a, b) => Number((BigInt(a) * BigInt(b)) % MODB);

    // ------------------------------------------------------------
    // STEP 1: Extract all NON-ZERO digits and their original positions
    // --------------------------------------------------

3754. Concatenate Non-Zero Digits and Multiply by Sum I

You are given an integer n. Form a new integer x by concatenating all the non-zero digits of n in their original order. If there are no non-zero digits, x = 0. Let sum be the sum of digits in x. Return an integer representing the value of x * sum.
/**
 * @param {number} n
 * @return {number}
 */
var sumAndMultiply = function(n) {
    // Step 1: build x by concatenating non-zero digits
    let s = String(n);
    let filtered = "";
    for (let ch of s) {
        if (ch !== '0') filtered += ch;
    }

    let x = filtered.length === 0 ? 0 : Number(filtered);

    // Step 2: compute digit sum of x
    let sum = 0;
    while (x > 0) {
        sum += x % 10;
        x = Math.floor(x / 10);
    }
