How does memoization optimize the recursive solution for the 0/1 Knapsack problem?
It sorts the items by their weight-to-value ratio.
It uses a greedy approach to select items.
It transforms the problem into a simpler, equivalent problem.
It stores the results of overlapping subproblems to avoid redundant computations.
In the context of Matrix Chain Multiplication, what do the dimensions of a matrix determine?
The number of rows and columns in the matrix, affecting multiplication compatibility and cost.
The values stored within the matrix.
The order in which the matrix was created.
The type of data stored in the matrix (integer, float, etc.).
How does the recursive solution for Matrix Chain Multiplication break down the problem into smaller subproblems?
By transposing each matrix before multiplication to potentially reduce operations.
By considering all possible pairings of adjacent matrices to multiply.
By dividing the matrices into halves and recursively multiplying the sub-matrices.
By sorting the matrices based on their dimensions and multiplying them in order.
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.
