LeetCode Solutions

This repository contains my solutions to various LeetCode problems implemented in C++, organized by category.

Purpose

The main goals of this repository are (according to Claude 3.7 Sonnet):

• Document my problem-solving approach for LeetCode problems
• Provide optimized and well-commented solutions
• Create a reference for interview preparation
• Track my progress in mastering algorithms and data structures

How to Use

Prerequisites

• GNU Make
• C++ compiler with C++23 support (Currently clang++ is hardcoded)

Compiling and Running Solutions

Example:

./run src/array/2sum.cpp

Currently, the build flags are hardcoded with -O3 and ASAN enabled.

Testing the solutions

Each solution's source file may include one or more test cases of the form: // TEST: [STDIN] -> [STDOUT]. The command ./test collects and runs all these these tests and reports the results (requires Python 3).

You can optionally specify which tests to run using substring matching against the source path, e.g. ./test -k src/array/two_sum.cpp, or add any other command line arguments of pytest.
