Enhanced fork of the LeetCode VS Code extension with Daily Challenges support and C++ Debug Templates.

# Install and try the new featuresgit clone https://github.com/su-mt/vscode-leetcode.gitcd vscode-leetcodenpm run compilevsce packagecode --install-extension vscode-leetcode-0.18.5.vsix

✨ What's immediately available:

• 📅Daily Challenges in Explorer panel
• 🔧Auto-generated C++ debug templates with real method names (📹 See Demo)
• ⚡Smart caching for faster loading
• 🎯Type-aware variable generation (vector<string>,vector<int>, etc.)

This fork extends the originalLeetCode VS Code Extension with several powerful new features while maintaining full backward compatibility.

TheDaily Challenges feature adds a dedicated section to your LeetCode Explorer, allowing you to:

• 🔍View Today's Challenge - Instantly see the current daily coding problem
• 📚Browse History - Access up to 30 days of past daily challenges
• 🎯Track Progress - See which daily challenges you've completed
• ⚡Fast Loading - Smart caching ensures quick access without API spam
• 🌍Global Support - Works with both international and Chinese LeetCode

1. Access Daily Challenges

   • Open VS Code
   • Go to the LeetCode Explorer panel
   • Find the new "📅 Daily Challenges" section

2. Solve Today's Challenge

   • Click on today's challenge
   • VS Code will open the problem description
   • Code and submit as usual

3. Review Historical Challenges

   • Expand the Daily Challenges section
   • Browse through past challenges
   • See your completion status at a glance

TheEnhanced C++ Debug Templates feature provides intelligent auto-generation of debug code for C++ problems, making testing and debugging significantly easier.

// @lc code=startclassSolution {public:    vector<int>twoSum(vector<int>& nums,int target) {    }};// @lc code=end

#include<iostream>...<headers>...usingnamespacestd;/* * @lc app=leetcode id=1 lang=cpp * * [1] Two Sum*/// @lc code=startclassSolution {public:    vector<int>twoSum(vector<int>& nums,int target) {    }};// @lc code=endintmain(){    Solution sol;// Тестовые данные:    vector<int> arr1 = {2,7,11,15};int num2 =9;    vector<int> arr3 = {3,2,4};int num4 =6;    vector<int> arr5 = {3,3};auto result = sol.twoSum(arr1, num2);return0;}

Watch the Enhanced C++ Debug Templates in action:

The demo shows:

• 🔍Automatic parsing of Input examples from problem description
• 🧠Smart type detection (vector<string>,vector<int>,int, etc.)
• 🎯Real method name extraction (twoSum,longestCommonPrefix, etc.)
• ⚡Instant template generation with properly typed variables
• 🔧Parameter count matching (only uses required number of params)

1. Extract Test Data: Parses problem description forInput: examples
2. Decode HTML: Converts HTML entities (" →") to clean values
3. Detect Types: Analyzes values to determine C++ types
4. Extract Method: Finds real method name and parameter count from code
5. Generate Template: Creates properly typed variables and method call

// Arraysvector<int> nums = {1,2,3};// from [1,2,3]vector<string> strs = {"a","b","c"};// from ["a","b","c"]// Primitivesstring s ="hello";// from "hello"int target =42;// from 42double rate =3.14;// from 3.14bool flag =true;// from true// Method calls with correct parameter countauto result = sol.twoSum(nums, target);// Only uses required params
