In a recursive solution for the LIS problem, what is the overlapping subproblem?
Calculating the sum of elements in a given range.
Determining the LIS for the same sub-sequence starting at different indices.
Finding the maximum element in a subarray.
Sorting the given sequence in ascending order.
In the memoized solution for the Fibonacci sequence, what data structure is typically used to store previously computed values?
Queue
Graph
Array
Stack
What is the role of the coin denominations in the Coin Change problem?
They determine the maximum capacity of the knapsack.
They represent the values of the items you can choose from.
They influence the order in which subproblems are solved.
They are not essential to the problem definition.
What is the base case in the recursive solution for the LCS problem?
When both input sequences have only one character.
When the last characters of both input sequences are the same.
When both input sequences are empty.
When one or both input sequences are empty.
What does 'LCS' stand for in the context of Dynamic Programming?
Longest Common Subsequence
Longest Common String
Linear Computational Sequence
Largest Common Subset
In the context of the Longest Common Subsequence (LCS) problem, what does a cell (i, j) in the tabulation table represent?
The length of the LCS of the prefixes of the two strings up to indices i and j
The number of characters that are common between the two prefixes
Whether the characters at indices i and j in the two strings are equal
The maximum length of a subsequence ending at indices i and j
What is the purpose of memoization in the context of the recursive Matrix Chain Multiplication solution?
To reduce the space complexity by storing only the essential intermediate matrices.
To enable backtracking and finding all possible optimal parenthesizations.
To transform the recursive solution into an iterative one.
To avoid redundant computations by storing and reusing the results of already solved subproblems.
In the context of the 0/1 Knapsack problem, what does the '0/1' signify?
An item can either be fully included or excluded from the knapsack.
The value of each item can be either 0 or 1.
The weight of each item can be either 0 or 1.
You can only pick a maximum of one item from the available set.
What is the time complexity of the tabulated dynamic programming approach for Levenshtein distance, given two strings of lengths m and n?
O(m+n)
O(2^(m+n))
O(n)
O(m*n)
How does memoization improve the efficiency of the recursive solution for LIS?
It converts the recursive solution into a dynamic programming solution.
It sorts the input sequence to reduce the search space.
It stores the results of overlapping subproblems to avoid recomputation.
It eliminates tail recursion, making the solution iterative.
