The explanation was very clean, and I liked how you explained it slowly so that even beginners could follow along. In particular, showing the thought process step-by-step was a huge help! I still have many problems left to solve, but I think this will be very helpful for my coding test preparation.

LeetCode explained by Dalle, a Korean developer working at a Silicon Valley startup! This is a practical LeetCode problem-solving course that doesn't just provide answer codes, but compares multiple approaches for each problem, analyzes time and space complexity together, and explains why certain solutions are more efficient. First, we write the most intuitive approach and analyze its time/space complexity to identify bottlenecks and improvement points. Then, we explore alternative approaches applying various data structures and algorithmic techniques, comparing the performance differences and pros and cons of each method. Through this, it helps you develop problem-solving skills to design efficient solution strategies on your own when facing new problems.

LeetCode Essential Problem Solving for Passing Coding Tests

Thank you so much for leaving such a valuable review! I'm glad to hear that the pace of the solutions and the explanation style were helpful. It might seem like a lot of problems at first, but as you solve them one by one, you'll eventually reach a point where it all feels familiar. If you ever get stuck while studying, please feel free to ask questions anytime. 🙂

アメリカ・シリコンバレーのスタートアップで働く韓国人開発者、ダレが教えるLeetCode！単に正解コードだけを教える方式ではなく、各問題に対して複数のアプローチを比較し、時間計算量と空間計算量を一緒に分析しながら、なぜある解法がより効率的なのかを説明する実践型LeetCode問題解説講座です。まず最も直感的なアプローチを作成し、その方法の時間/空間計算量を分析してボトルネックと改善ポイントを把握し、その後様々なデータ構造とアルゴリズム的手法を適用した他のアプローチを見ながら、各方式の性能差と長所短所を比較します。これを通じて、新しい問題に直面した時に自ら効率的な解決戦略を設計できる問題解決能力を身につけられるようサポートします。
