Question 1.
What is memoization?
Show hintHide hint
Think about functions that call themselves.
Question 2.
How do you handle a hole in a grid path count?
Show hintHide hint
Remember the path continuity.
3Question 3.
What is the primary advantage of using dynamic programming?
- A. It computes only needed values
- B. It systematically solves all subproblems
- C. It runs slower than recursion
Show hintHide hint
Think about the difference in approach between both methods.
4Question 4.
True or False: Memoization will calculate every possible value in advance.
- True
- False
Show hintHide hint
Remember how memoization works.
Question 5.
Given a 6x6 grid with holes at (2,1), (2,3), and (4,5), calculate the number of paths from (0,0) to (5,5).
Show hintHide hint
Visualize the grid and observe how holes restrict movement.
Question 6.
Design a function in pseudo-code to implement grid path counting using dynamic programming with hole handling. Explain its efficiency.
Show hintHide hint
Focus on looping through each cell and applying path calculations iteratively.
