Challenge Problems
Push your limits with advanced challenges
You have a grid of size 6x6 with holes at (2, 2), (3, 3), and (1, 5). Calculate the number of unique paths from (0, 0) to (5, 5). What strategies will you employ?
💡 Hint: Focus on filling values in a structured manner and adjust according to hole placements.
Compare the efficiency of dynamic programming versus memoization in a scenario where 70% of the grid is filled with holes. Discuss any trade-offs.
💡 Hint: Analyze how the structure of the grid and placement of holes contribute to each method’s computational efficiency.
