Explore detailed LeetCode solutions in Java, C++ / Cpp, and Python with step-by-step explanations. Each solution includes time and space complexity analysis to help you optimize your coding skills for interviews and competitive programming.

In addition to core solutions, this collection is designed to help you understand why a particular approach works, not just how to write the code. Problems are explained using clear logic, edge-case handling, and optimal data structures commonly expected in technical interviews.

The solutions cover a wide range of difficulty levels, including Easy, Medium, and Hard problems, with a strong focus on frequently asked interview questions from arrays, strings, linked lists, trees, graphs, dynamic programming, greedy algorithms, and recursion. Wherever applicable, multiple approaches are discussed to compare brute-force methods with optimized solutions.

Whether you are preparing for FAANG interviews, practicing for online coding contests, or strengthening your problem-solving fundamentals, these LeetCode solutions provide a structured and practical learning path. The content is regularly updated to align with the latest problem patterns and interview trends.
