-# CLAUDE.md
-
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Project Overview
-This is a LeetCode solutions repository organized by date and problem type. The codebase contains solutions in multiple languages including C, C++, Go, and Java. The repository is structured with:
-- Date-based directories (e.g., `23/04/`, `25/11/`) containing individual problem solutions
-- Data structure implementations in the `dataStruct/` directory (LinkedList, Heap, Tree, etc.)
-- Special categories like "dynamic planning" and "else"
-
-## Development Commands
-
-### Building and Running Code
-Since this repository contains individual solution files rather than a unified project, compilation and execution is done per file:
-
-**For C/C++ files:**
-```bash
-# Compile C file
-gcc -o solution filename.c
-
-# Compile C++ file
-g++ -o solution filename.cpp
-
-# Run the compiled executable
-./solution
-```
-
-**For Go files:**
-```bash
-# Run Go file directly
-go run filename.go
-
-# Build Go executable
-go build filename.go
-```
-
-**For Java files:**
-```bash
-# Compile Java file
-javac filename.java
-
-# Run Java program
-java filename
-```
-
-### Testing Solutions
-There are no automated tests in this repository. Each solution should be tested manually by:
-1. Compiling/running the solution file directly
-2. Verifying output against expected LeetCode test cases
-3. Using the data structure helper functions (like `list()`, `len()`, `creatRandomTree()`) for debugging
-
-## Code Architecture
-
-### Data Structures
-The repository includes custom implementations of common data structures:
-- **LinkedList**: Defined in `dataStruct/LinkedList/lists.h` with `ListNode` struct and utility functions (`createRandomList`, `list`, `array`, `len`)
-- **Tree**: Defined in `dataStruct/Tree/Tree.h` with `TreeNode` struct and `creatRandomTree` function
-- **Heap**: Basic template implementation in `dataStruct/Heap/Heap.h`
-- **Queue**: Priority queue implementation in `dataStruct/Queue/PriorityQueue.c`
-
-### File Organization
-- **Date directories**: Solutions organized by year/month (e.g., `25/11/` for November 2025)
-- **Language variants**: Some problems have multiple language implementations (e.g., `3005.go`, `3005.cpp`, `3005.java`)
-- **Utility headers**: Common tools and data structures in `tools.h` and the `dataStruct/` directory
-
-### Common Patterns
-- Solutions often include debug output functions for visualizing data structures
-- Random data generation functions are provided for testing (`createRandomList`, `creatRandomTree`)
-- Header files use proper include guards and pragma once directives
-
-When working on new solutions, follow the existing patterns and place files in the appropriate date directory based on when the solution was created.
