Question 1.
What is memoization?
Show hintHide hint
Think about redundant calculations in recursion.
Question 2.
Define the Fibonacci sequence.
Show hintHide hint
How do the numbers grow?
3Question 3.
What is the primary benefit of memoization?
- Increases function call overhead
- Stores results to prevent re-computation
- Does not optimize performance
Show hintHide hint
Think about computational efficiency.
4Question 4.
True or False: Dynamic programming is an iterative approach that builds solutions stepwise.
- True
- False
Show hintHide hint
Consider how values are calculated.
Question 5.
Design a memoized function to compute the factorial of a number. Explain how the memoization affects its time complexity.
Show hintHide hint
Store results after computation and check before recalculating.
Question 6.
Analyze a recursive method trying to solve the tower of Hanoi problem. Explain how dynamic programming could be applied to optimize it.
Show hintHide hint
Consider how overlapping subproblems might arise in this scenario.
