NeetCode Solutions in Java 21

Project Description

This repository contains solutions to NeetCode problems implemented in Java 21. The main goal of this repository is to provide a comprehensive collection of solutions for various data structures, algorithms, sorting techniques, and design patterns, showcasing clean code and thorough testing practices.

Structure

The repository is organized into multiple subprojects, each representing a different problem or topic. Each subproject contains its own README.md with specific details about the implementation and testing.

Subprojects

  • Design Patterns: Implementation of design patterns.
  • Graphs: Solutions to graph-related problems.
  • Data Structures: Implementation of data structures.
  • Sorting: Implementation of sorting algorithms.

Features

  • Solutions to various NeetCode problems.
  • Implementation of data structures, algorithms, and design patterns in clean Java code.
  • Comprehensive test cases for each implementation.
  • Detailed documentation for each subproject.
  • Full test coverage for all implementations.

Requirements

  • Java 21

Usage

Clone the repository and navigate to the specific subproject directory. Follow the instructions in the subproject's README.md to compile and run the code.

git clone https://github.com/samvel-aivazian/neetcode.git
cd neetcode

Running a Specific Subproject

  1. Navigate to the subproject directory:

    cd <subproject_directory>

    Replace <subproject_directory> with the path to the specific subproject you want to run. For example:

    cd core_skills/implement_data_structures/design_singly_linked_list

  2. Compile the Java files:

    javac -cp . org/samvelaivazian/<subproject>/*.java

    Replace <subproject> with the package name specific to the subproject. For example:

    javac -cp . org/samvelaivazian/linkedlist/*.java

  3. Run the test class:

    java -ea org/samvelaivazian/<subproject>/<TestClassName>

    Replace <subproject> with the package name and <TestClassName> with the name of the test class specific to the subproject. For example:

    java -ea org.samvelaivazian.linkedlist.LinkedListTest
