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]

Ask for maximum profit. Topic Ideas:This is a dynamic planning issue. It is not difficult to think of splitting the entire array into two parts. Then use two arrays

Question Say you have an array for which the ith element is the price of a given stock on day I. If you were only permitted to complete at most one transaction (ie, buy one and every one share of the stock), design an algorithm to find the maximum profit. Answer To maximize the benefits, buy at the lowest price and se

Title Link: click~/* Test instructions: An array, the element I represents the price of the stock of day I, only allowed to buy and sell once, for maximum profit *//** * Ideas: Two pointers, one scan the entire array, the other record the minimum value of the scanned element * During the scan, update the minimum value while updating the maximum profit * Maximum profit: Max (A[j]-a[i]), J>i */class

Given a vector, the vector represents the price of a stock in the first day, Y to make the stock yield the largest should be bought on the day I, the first i+n days to sell, to find out the value of the maximum profit is how muchIdea: Record the minimum value with a variable, a variable record the maximum benefit, scan the price from beginning to end, when scanning to the price of the day I, if the price is

Say you have an array for which the ith element is the price of a given stock on day I. Design an algorithm to find the maximum profit. You may complete at most two transactions.
