Question 1
What is the primary advantage of memoization?
- It optimizes recursive calculations.
- It complicates recursive functions.
- It generates new pathfinding algorithms.
💡 Hint: Consider what happens when you need a result that has already been computed.
Question 2
True or False? Dynamic programming computes all possible solutions before storing results.
- True
- False
💡 Hint: Think about how dynamic programming builds solutions from smaller parts.

Challenge Problems
Push your limits with challenges.
Question 1
Determine the total number of paths in an 8x8 grid that has holes at (3,3) and (6,2). Use dynamic programming principles.
💡 Hint: Build your table row by row; how do you handle the holes?
Question 2
Construct a comparison chart of memoization versus dynamic programming detailing time complexity, situation applicability, and efficiency. Provide examples for each.
💡 Hint: Consider the advantages of structure vs. the recursive approach.
