Dynamic Programming Data Structure And AlgorithmMedium

Consider the matrices P, Q and R which are 10 x 20, 20 x 30 and 30 x 40 matrices respectively. What is the minimum number of multiplications required to multiply the three matrices?

Correct Answer: A — 18000

The minimum number of multiplications are 18000. This is the case when the matrices are parenthesized as (P*Q)*R.
