LeetCode Problem Solutions

Overview

This repository contains a collection of solutions to various LeetCode problems implemented in both Java and C++. The solutions cover a range of algorithmic challenges commonly found on LeetCode, including string manipulation, array processing, and classic problem-solving patterns.

Key Solution Folders

• C++/AddTwoNumbers/
  Solution for the "Add Two Numbers" problem using singly-linked lists.
• C++/MedianoTwoSortedArrays/
  Solution for finding the median of two sorted arrays.
• C++/TwoSum/
  Solution for the classic "Two Sum" problem.
• C++/longestSubstring/
  Implementation for finding the length of the longest substring without repeating characters.
• Java/ConditionalsIf/
  Solutions demonstrating conditional logic, including a Blackjack card game logic.
• Java/StringSolving/
  String manipulation problems and log formatting utilities.

How to Use

Browse the language-specific folders (C++ and Java) to find implementations of various LeetCode problems. Each problem typically contains a README.md and source code files demonstrating one or more approaches.

Example: Running a Solution in Java

Navigate to the relevant Java folder and execute the main class, for example:

cd Java/StringSolving/src/main/java/com/mycompany/stringsolving
javac LogLevels.java
java com.mycompany.stringsolving.LogLevels

Example: Running a Solution in C++

The C++ folders may contain Java code for demonstration purposes. Follow the same steps as above, replacing the package paths as needed.

Documentation & Translations

• Additional documentation is available in the docs/ directory.
• An Arabic translation of the readme is available under translations/README_ar.md.
