Q. In the 0/1 Knapsack problem, what does the '0/1' signify?
A.
Items can be divided
B.
Items can be taken or left
C.
Items can be taken multiple times
D.
Items have no weight
Solution
The '0/1' in the 0/1 Knapsack problem signifies that each item can either be taken (1) or left (0), meaning items cannot be divided or taken multiple times.
Q. In the context of dynamic programming, what does 'memoization' refer to?
A.
Storing results of expensive function calls and reusing them
B.
Sorting data before processing
C.
Using a stack to manage function calls
D.
Creating a binary tree for data storage
Solution
Memoization is a technique used in dynamic programming to store the results of expensive function calls and reuse them when the same inputs occur again.
Correct Answer:
A
— Storing results of expensive function calls and reusing them
Q. In the context of dynamic programming, what does the term 'memoization' refer to?
A.
Storing results of expensive function calls
B.
Sorting data for faster access
C.
Creating a tree structure for data storage
D.
Using a stack to manage function calls
Solution
Memoization refers to the technique of storing the results of expensive function calls and returning the cached result when the same inputs occur again.
Correct Answer:
A
— Storing results of expensive function calls
Q. In the context of dynamic programming, what is memoization?
A.
A method to optimize space complexity
B.
A technique to store results of expensive function calls
C.
A way to reduce time complexity
D.
A strategy for greedy algorithms
Solution
Memoization is a technique used in dynamic programming to store the results of expensive function calls and reuse them when the same inputs occur again, thus optimizing the computation.
Correct Answer:
B
— A technique to store results of expensive function calls
