⚡ Last Minute Revision Tips
- Review time and space complexities for all major sorting algorithms (Quick sort, Heap sort, Insertion sort, Radix sort).
- Practice dry-running tree traversals (inorder, preorder, postorder) and stack-based infix to postfix expression conversions.
- Memorize the step-by-step execution procedures for graph algorithms including Dijkstra's, Prim's, and Kruskal's.
- Be clear on how pointers are manipulated during linked list insertions, deletions, and queue operations.
- Recall the fundamental differences between design strategies like Greedy method versus Dynamic Programming.
📝 Exam Strategy
⏱️ Time Management
- Allocate time proportionally based on the marks assigned to descriptive questions versus algorithm design problems.
- Do not spend excessive time tracing long graph or tree operations; write out steps methodically.
✍️ Answer Writing Tips
- Structure algorithm answers with a clear description, pseudo-code or steps, and complexity analysis (time and space).
- Use point-by-point comparisons when comparing structures like singly linked lists versus doubly linked lists.
📐 Diagram Presentation
- Draw clear, labeled diagrams for tree structures, binary search trees, linked list nodes, and graph adjacency representations.
- Illustrate sorting steps or tree traversal paths with intermediate snapshot diagrams where helpful.
⚠️ Common Mistakes to Avoid
- Forgetting to handle edge cases in linked list operations (e.g., empty list or single node).
- Confusing the mechanics of Depth-First Search (using stacks/recursion) with Breadth-First Search (using queues).
