"Introduction to Algorithms" is a widely used textbook that provides a comprehensive overview of algorithms, which are step-by-step procedures for solving problems. The book covers a variety of topics, including sorting, searching, and graph algorithms, making it suitable for both beginners and advanced learners. It emphasizes the importance of algorithm efficiency and complexity analysis. The authors, Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, and Clifford Stein, present algorithms in a clear and structured manner, often using pseudocode to illustrate concepts. This approach helps readers understand the underlying principles and apply them to real-world problems in computer science and software development.
