Here’s an overview of the key concepts and structures you might encounter: Basic Data Structures Arrays Fixed-size, contiguous memory. Fast access but expensive resizing. Linked Lists Singly Linked List, Doubly Linked List, Circular Linked List. Dynamic size, efficient insertions/deletions. Stacks Last In, First Out (LIFO). Useful for recursive algorithms, undo mechanisms. Queues First In, First Out (FIFO). Useful for scheduling, breadth-first search. Hash Tables Key-value pairs, fast lookups. Handling collisions via chaining or open addressing. Advanced Data Structures Trees Binary Tree, Binary Search Tree (BST), AVL Tree, Red-Black Tree. Hierarchical structure, efficient search/insert/delete. Heaps Binary Heap, Min-Heap, Max-Heap. Priority Queue implementation, efficient maximum/minimum retrieval. Graphs Representations: Adjacency Matrix, Adjacency List. Types: Directed, Undirected, Weighted, Unweighted. Algorithms: DFS, BFS, Dijkstra's, Kruskal's, Prim's. Tries Prefix trees, efficient for string manipulations. Key Algorithms Sorting Algorithms Bubble Sort, Selection Sort, Insertion Sort. Merge Sort, Quick Sort, Heap Sort. Time complexities, use cases. Searching Algorithms Linear Search, Binary Search. Depth-First Search (DFS), Breadth-First Search (BFS). Dynamic Programming Overlapping subproblems, optimal substructure. Memoization, Tabulation. Greedy Algorithms Local optimum leads to global optimum. Examples: Huffman Coding, Kruskal's Algorithm. Divide and Conquer Divide problem into subproblems, solve recursively, combine solutions. Examples: Merge Sort, Quick Sort. Implementing in Java Utilize Java Collections Framework for dynamic data structures (ArrayList, LinkedList, HashMap, etc.). Create custom implementations for understanding underlying mechanics. Use built-in algorithms from java.util.Collections.
