Say you has an array for which the i-th element is the price of a given-stock on day I.If you were-permitted-to-complete at most one transaction (ie, buy one and sell one share of the stock), design an AL Gorithm to find the maximum profit.First, the problem is converted to a mathematical language: array a[n], and for any i The results can be obtained using O (n^2) method.The following dynamic planning methods are analyzed:For input prices[n], if know

Say you has an array for which the i t H element is the price of a given stock on day i .Design an algorithm to find the maximum profit. You are in most of the transactions.Note:Engage in multiple transactions on the same time (ie, you must sell the stock before you buy again).Thinking of solving problemsCreate two arrays left and right store the maximum benefits that can be obtained from the left and right sides of an element, respectively. That

Say you has an array for which the i-th element is the price of a given-stock on day I.If you were-permitted-to-complete at most one transaction (ie, buy one and sell one share of the stock), design an AL Gorithm to find the maximum profit.Solution 1:Find each minimum, find a maximum value after each minimum, and calculate the maximum benefit. Compare each of the maximum benefits. Public classSolution { Public intMaxprofit (int[] prices) { if(
