Advanced Problem-Solving Methods and Search Algorithms

This course features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. Take your algorithmic thinking to the next level by mastering advanced problem-solving techniques used in top technical interviews. This course equips you with efficient strategies like stacks, sliding window, two pointers, and binary search, enabling you to solve complex problems with optimized approaches and improved performance. You will begin by exploring stacks and their practical applications in solving problems such as valid parentheses, reverse polish notation, and next greater elements. From there, the course transitions into the sliding window technique, helping you tackle substring and window-based optimization problems with clarity and efficiency. As you progress, you will dive into the two-pointer method and interval-based problem solving, followed by mathematical and geometric challenges like spiral matrices. The course culminates with an in-depth understanding of binary search, including advanced applications such as searching in rotated arrays and optimizing search over ranges. This course is ideal for learners with prior knowledge of basic data structures and algorithms who want to strengthen their problem-solving skills. It is best suited for intermediate learners preparing for coding interviews or aiming to improve algorithmic efficiency. By the end of the course, you will be able to apply advanced problem-solving patterns, optimize search strategies, and confidently solve complex algorithmic challenges across a wide range of scenarios.
