Suppose that instead of maintaining the table w[I, j], we computed the value of w(I, j) directly

Question:

Suppose that instead of maintaining the table w[I, j], we computed the value of w(I, j) directly from equation (15.12) in line 9 of OPTIMAL-BST and used this computed value in line 11. How would this change affect the asymptotic running time of OPTIMAL-BST?

(15.12)
