LeetCode Helper

About

LeetCode Helper
A Chrome extension that provides progressive hints for LeetCode problems to help you learn without spoiling solutions.

The Problem
When stuck on LeetCode problems, students often jump straight to solutions, missing the learning opportunity. LeetCode Helper provides progressive hints that guide your thinking without spoiling the answer.

How It Works
LeetCode Helper uses pattern recognition to identify common algorithmic patterns in problems and provides hints at three levels:

Level 1: High-level guidance (data structures & patterns)
Level 2: Strategic reasoning (time/space trade-offs)
Level 3: Algorithm steps (pseudocode direction)

The extension recognizes 15+ common DSA patterns:
- Two Sum / Hash Map patterns
- Linked List manipulation
- Stack/Queue problems
- Binary Search
- Sliding Window
- Dynamic Programming
- Graph traversal (BFS/DFS)
- Two Pointers
- Backtracking
- Prefix Sum
- Greedy algorithms
- And more
