Given matrices of various dimensions, evaluate the computational cost of each multiplication order. Specifically, for matrices A(2x3), B(3x4), C(4x2), and D(2x5), determine which order minimizes the total operations.
💡 Hint: Countdown from each split and compare the sums.
Create a recursive function that implements the cost calculation method for any given set of matrix dimensions.
💡 Hint: Use the structure we discussed in class to outline your function.
