- The Old: A grandmother performing puja (prayer) with physical flowers and incense.
- The New: Her grandson streaming a gaming live stream while ordering groceries via Zepto (10-minute delivery).
- The Blend: During the pandemic, millions watched digital aartis (prayer ceremonies) on YouTube, proving that technology doesn't kill faith; it merely changes the venue.

- Task: Solve 20 recurrence relation problems.
- Divide and conquer: Break a problem into subproblems, solve recursively, and combine results. Examples: merge sort, quicksort (partitioning variant), binary search, Karatsuba multiplication.
- Dynamic programming: Solve overlapping subproblems and reuse results via memoization or tabulation. Examples: shortest paths (Bellman–Ford), knapsack, edit distance.
- Greedy algorithms: Make locally optimal choices hoping to reach a global optimum; requires proof of correctness via exchange argument or matroid structure. Examples: Prim’s and Kruskal’s MST algorithms, Dijkstra’s shortest paths (nonnegative weights), Huffman coding.
- Backtracking and branch-and-bound: Systematically explore solution spaces with pruning. Examples: constraint satisfaction, exact combinatorial search.
- Randomized algorithms: Use randomness to simplify design or improve expected performance. Examples: randomized quicksort, Bloom filters, Monte Carlo/Las Vegas algorithms.
- Approximation algorithms: Provide near-optimal solutions with provable bounds when exact solutions are intractable (NP-hard problems). Examples: vertex cover approximation, PTAS/FPTAS frameworks.
- Streaming and online algorithms: Process inputs arriving in sequence with limited memory; use competitive analysis for performance guarantees. Examples: count-min sketch, caching algorithms (LRU), K-server problems.
- Parallel and distributed algorithms: Design for multiple processors or networked nodes, with attention to communication cost, concurrency, and synchronization.
