# AI Chrome extension for LeetCode & NeetCode: Socratic hints without spoiling the code.

Highlight problem constraints, tricky recurrence relations, or editorial solutions on LeetCode and NeetCode to get Socratic hints without spoiling the full code.

> **Best fit:** Best for software engineers preparing for coding interviews on leetcode.com, neetcode.io, and HackerRank who want progressive hints rather than solution spoilers.

## Live Webpage Walkthrough

- **Source:** LeetCode Problem — Monotonic Deque Editorial Line (`leetcode.com/problems/shortest-subarray-with-sum-at-least-k`)
- **Recommended Context Mode:** Basic

**Highlighted Passage:**
> Constraints: 1 <= nums.length <= 10^5, -10^5 <= nums[i] <= 10^5.
Editorial: While the current prefix sum is <= the prefix sum at the back of the deque, we pop from the back of the deque before pushing the current index i.

**User Question (Shortcut):** "Explain why we pop from the back of the deque when prefix[i] <= prefix[back]—why can that older index never be optimal?"

**Vezz me On-Screen Answer:**
**Why `back` becomes strictly dominated once a smaller `prefix[i]` arrives later (`i > back`)**:
For any future right endpoint `r > i`:
1. **Larger Sum**: `prefix[r] - prefix[i] >= prefix[r] - prefix[back]` (makes it easier to reach `>= k`).
2. **Shorter Subarray**: Index `i` is *closer* to `r` (`r - i < r - back`).
Because `i` gives **both a larger sum and a shorter length** than `back`, `back` can never be the optimal start of a shortest valid subarray again—so we safely discard it!

**Suggested Follow-Ups:**
- "Walk through a 4-element dry run with negative numbers to show this deque in action."
- "Why does a normal sliding window two-pointer approach fail when `nums[i]` can be negative?"

## Step-by-step workflow

1. **Highlight the problem statement + Constraints block when stuck**: Include the `Constraints:` lines—$N \le 15$ points to $O(2^N)$ bitmask/backtracking, while $N \le 10^5$ requires $O(N)$ or $O(N \log N)$.
2. **Run the Socratic Tutor preset for a zero-code nudge**: Press your shortcut and use our Socratic Tutor preset so Vezz me asks you a guiding question about the invariant instead of dumping the solution.
3. **Highlight confusing lines in the Editorial or Solutions tab afterward**: When reviewing community solutions, highlight the specific DP transition or pointer invariant you don't understand and ask Vezz me why it holds.

## Why '0ms Beats 100%' community posts are terrible teachers

Top-voted posts in the LeetCode Solutions tab are often 8-line C++ or Python golf snippets with single-letter variables (`l, r, dp, cur`) and zero proof of correctness.

- Translates cryptic DP state transitions and bit-manipulation tricks into clear loop invariants
- Uses input constraints (`1 <= n <= 10^5`) to teach you how to rule out $O(N^2)$ approaches before writing a line of code
- Zero injected buttons over the Monaco code editor—your coding workspace stays clean

## Using AI for Coding Interview Prep

Comparing Socratic hint coaching with auto-solver extensions.

| Approach | Strengths | Tradeoffs |
| --- | --- | --- |
| Vezz me + Socratic Tutor Preset | Progressive hints without code spoilers + deep invariant explanations on editorials | Designed for active learning rather than copy-pasting answers |
| Dedicated 'LeetCode Auto-Solver' extensions | Generating full code solutions immediately | Spoils the problem immediately and injects overlays into the code editor |
| Reading raw community solution tabs | Seeing multiple language implementations | Shows *what* the code is, but rarely explains *why* the greedy/DP invariant is valid |

## Frequently asked questions

### How do I make sure Vezz me doesn't accidentally show me the code solution?

Use our Socratic Tutor preset (which strictly gives hints and guiding questions) or end your prompt with: 'Give me a 1-sentence conceptual hint only—do NOT write code.'

### Can Vezz me analyze the time and space complexity of my own solution?

Yes! Highlight your own code in the editor or submission page, press your shortcut, and ask for the exact worst-case time and auxiliary space complexity.

### Does it work on NeetCode.io, HackerRank, and Codeforces?

Yes. It works on any algorithm platform in Chrome or Firefox.
