Data Structures Algorithms in Java – SECRETS to Ace LeetCode

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. In this course, you will explore advanced topics in recursion, backtracking, and object-oriented programming (OOP). You’ll dive deep into recursive techniques, starting with basic problems like Fibonacci numbers and binary search, and advancing to more complex challenges like quick sort, merge sort, and maze solving. Through various problem-solving exercises, you'll master recursion’s power to simplify problem-solving and improve efficiency. The course also covers the powerful technique of backtracking, emphasizing how to solve constraint satisfaction problems like Sudoku. You’ll then transition to object-oriented programming, learning about classes, objects, inheritance, encapsulation, and polymorphism—core principles that underpin modern software design. Additionally, the course explores data structures such as linked lists, stacks, queues, and binary trees, with a focus on their application in solving real-world problems. By working through a series of LeetCode problems, you’ll develop a strong grasp of algorithmic thinking and efficient coding techniques, including recursion, backtracking, and OOP. By the end of the course, you will be able to implement advanced recursion techniques, solve backtracking problems, apply object-oriented principles in code, and work with essential data structures like linked lists and binary trees to solve complex algorithmic challenges.
