In a recursive solution for the LIS problem, what is the overlapping subproblem?
Sorting the given sequence in ascending order.
Determining the LIS for the same sub-sequence starting at different indices.
Finding the maximum element in a subarray.
Calculating the sum of elements in a given range.
Which of the following operations is NOT considered in calculating the Levenshtein distance between two strings?

Substitution
Swapping
What is the base case in the recursive solution for the LCS problem?
When one or both input sequences are empty.
When the last characters of both input sequences are the same.
When both input sequences have only one character.
When both input sequences are empty.
Why is the Coin Change problem considered a variation of the unbounded knapsack problem?
Both problems have the same time complexity.
The order in which you select the coins doesn't matter.
You can take multiple instances of the same coin denomination.
The solution always involves using all available coin denominations.
What is the purpose of memoization in the context of the recursive Matrix Chain Multiplication solution?
To transform the recursive solution into an iterative one.
To reduce the space complexity by storing only the essential intermediate matrices.
To avoid redundant computations by storing and reusing the results of already solved subproblems.
To enable backtracking and finding all possible optimal parenthesizations.
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(m*n)
O(2^(m+n))
O(n)
In the dynamic programming table for Levenshtein distance, what does the cell at index (i, j) typically represent?
The number of insertions required to transform the first string into the second string.
Whether the first i characters of the first string are identical to the first j characters of the second string.
The number of deletions required to transform the first string into the second string.
The edit distance between the first i characters of the first string and the first j characters of the second string.
How does memoization optimize the recursive solution for the 0/1 Knapsack problem?
It transforms the problem into a simpler, equivalent problem.
It stores the results of overlapping subproblems to avoid redundant computations.
It sorts the items by their weight-to-value ratio.
It uses a greedy approach to select items.
In a bottom-up tabulated solution for LIS, what does the table typically store?
The sum of elements in the LIS ending at each index.
The length of the LIS ending at each index.
The indices of elements in the LIS.
Boolean values indicating if an element is part of the LIS.
The Longest Common Subsequence problem exhibits which of the following properties that make it suitable for Dynamic Programming?
Divide and Conquer
Greedy Choice Property
Backtracking
Optimal Substructure and Overlapping Subproblems
