Challenge Problems
Push your limits with challenges.
Question 1
In a 6x6 grid with holes at (2,2) and (3,3), compute the number of paths to (5,5) through dynamic programming and illustrate your table.
💡 Hint: Start with your base cases and fill each cell considering blockage from holes.
Question 2
Construct a comprehensive table showing both memoized and dynamically programmed solutions for a 5x5 grid with four holes randomly distributed.
💡 Hint: Use both methods to fill the same grid and compare the resulting path counts, especially noting differences in efficiency.
