DSA With Java in One Month
Week 1: Foundations & Arrays

1. Java Basics Refresher (if needed): loops, conditional statements, functions/methods, and basic OOP.


2. Arrays: Single-dimensional, multi-dimensional arrays, basic operations (traversing, updating).


3. String Manipulations: Common string problems (e.g., reversing, palindrome check).


4. Two-Pointer Technique: Practice problems like finding pairs, triplets, etc.



Practice: Implement code daily on platforms like LeetCode or HackerRank to solidify your foundation.

Week 2: Recursion & Sorting/Searching

1. Recursion: Start with basics (factorial, Fibonacci), then move to problems like subsets and permutations.


2. Sorting Algorithms: Bubble Sort, Selection Sort, Insertion Sort, Merge Sort, Quick Sort (learn and implement each).


3. Searching Algorithms: Linear Search, Binary Search (focus on binary search variations, as they’re commonly asked).



Practice: Focus on solving problems that involve recursion and common sorting problems. Keep writing code from scratch without referencing solutions.

Week 3: Linked Lists, Stacks, Queues, and Hashing

1. Linked List: Single and doubly linked lists, operations (insertion, deletion, reversing), detecting cycles.


2. Stacks & Queues: Understand operations and applications (balancing parentheses, evaluating expressions).


3. Hashing: Understand HashMaps and HashSets; practice common hashing problems (like finding duplicates, frequency counting).



Practice: Work on small projects or focused problem sets with linked lists, stacks, and queues. Hashing problems are often short but logical, so aim for accuracy here.

Week 4: Trees, Graphs, and Dynamic Programming (DP)

1. Trees: Binary Trees, Binary Search Trees, and common operations (in-order, pre-order, and post-order traversals).


2. Graphs: Basics of BFS and DFS, simple applications (like finding connected components).


3. Dynamic Programming: Start with basic problems (Fibonacci, knapsack, coin change).



Practice: Focus on tree and graph traversal problems and a few beginner-level DP problems to strengthen your grasp on more complex DSA topics.

Extra Tips:

1. Time Management: Spend at least 2-3 hours daily on DSA, prioritizing quality over quantity in problem-solving.


2. Mock Interviews: Towards the end, do mock coding interviews to build confidence.


3. Revision: For every topic, revise your solutions and try to optimize if possible, as this will help in interviews.
