Finally, all profits can be counted. Public int maxPro

Questionsay you had an array for which the ith element was the price of a given stock on day i.design an algorithm to find The maximum profit. Transactions at the most K. For example, given prices = [4,4,6,1,1,4,2,5], and k = 2, return 6.Answer with DP solution. LOCAL[I][J] Represents the number of 0~i, up to J transactions, and the last trade must contain PRICES[J] (that is, the last day must be sold), the maximum value of the proceeds. GLOBAL[I][J]
