Challenge Problems
Push your limits with advanced challenges
Given a 5x5 grid with holes at (1,2), (2,2), and (3,3), calculate the total unique paths from (0,0) to (4,4).
💡 Hint: Construct a dynamic programming table or visualize the grid.
Design a function to compute paths in an arbitrary sized grid with variable hole placements. How does the algorithm shift with each new hole introduced?
💡 Hint: Consider how the grid values propagate.
