In the context of Matrix Chain Multiplication, what do the dimensions of a matrix determine?
The order in which the matrix was created.
The number of rows and columns in the matrix, affecting multiplication compatibility and cost.
The values stored within the matrix.
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 considering all possible pairings of adjacent matrices to multiply.

It converts the recursive solution into an iterative one.
It sorts the input strings to speed up comparisons.
It reduces the depth of the recursion tree.
What is the role of the coin denominations in the Coin Change problem?
They are not essential to the problem definition.
They represent the values of the items you can choose from.
