Acing Data Structures and Algorithms (DSA) in 30 days requires a structured plan and consistent effort. Here's a plan to help you achieve this goal: Week 1: Focus on understanding the basics of DSA and programming languages such as C++ or Java. Start with simple problems and implement basic data structures such as arrays, linked lists, and stacks. Week 2: Understand more complex data structures such as trees, graphs, and hash tables. Learn how to implement these structures and understand their time and space complexity. Week 3: Master algorithms such as sorting, searching, and dynamic programming. Learn about advanced data structures such as priority queues, AVL trees, and segment trees. Solve problems related to these data structures and algorithms. Week 4: Practice, Practice, Practice. Solve problems from different sources such as online platforms like LeetCode, HackerRank, and Codeforces. Try to solve at least two problems daily and analyze your code for optimization. Remember that consistent effort, dedication, and patience are key to achieving this goal. It is important to focus on understanding the concepts, rather than just memorizing them. Stay motivated and keep practicing. With this plan, you can ace DSA in 30 days.
