Write a recurrence that would be used in dynamic programming for the following problem: Given a rod of length n and an array A of prices that contain all prices of all the pieces smaller than n. Determine the maximum value obtained by cutting up the rod and selling the pieces. Note that you could sell the rod at its original length without cutting it.
