Challenge Problems
Push your limits with challenges.
Question 1
Calculate the number of unique paths in a grid with dimensions 5x5 but with holes at (2,2) and (3,3).
💡 Hint: Consider using dynamic programming to fill out each cell based on its neighbors.
Question 2
Demonstrate how using recursion for grid paths can lead to a time complexity issue. Define an example and show how memoization would resolve it.
💡 Hint: Think about overlapping subproblems and how caching can optimize the process.
