LeetCode Solutions

Welcome! This repository contains efficient solutions to LeetCode problems, written in modern, readable, and self-explanatory code.

C++ is the primary programming language used. For educational purposes, STL algorithms and/or data structures may sometimes be omitted in easy-level problems to illustrate concepts clearly.

Database-related problems are solved using PostgreSQL, and shell-related problems are solved using Bash. All solutions aim for optimal runtime complexity, and most of them achieve top runtime performance, often beating 100% of submissions.

What each solution file includes

• Time complexity analysis
• Space complexity analysis
• Runtime performance comparison with other solutions in the same language
• Link to the LeetCode submission
• Link to the solution post
• Link to the original LeetCode problem

⚠️ Memory performance comparisons are not included, as LeetCode does not provide accurate measurements for this metric. Please refer to the space complexity analysis instead.
