Question 1
Given matrices A(5x10), B(10x3), and C(3x8), calculate the total operations for both (AB)C and A(BC). Which order is more efficient?
💡 Hint: Use the dimensions to derive the number of operations required explicitly.
Question 2
Imagine you have four matrices of varying dimensions. Devise an algorithm to compute the most operationally efficient multiplication order. Write the pseudo-code.
💡 Hint: Think in terms of breaking down the problem into smaller segments and compute their costs recursively.
