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

The normal "price increase, price decline" in the case of synchronization, there is no need to pay special attention to, should be paid attention to in the "price deviation" situation, the sale of stocks should be particularly analyzed.There is a need to correct a problem that has been overlooked in a price analysis. The real reason for the increase in price increases in addition to the rising price of follow-up funds in a timely manner, the existence and gush of large profit disk is another imp

Topicthe best time to buy and sell stocksSuppose there is an array, the first element of which is the price of a given stock in the first day. If you are allowed to complete only one transaction at most (for example, buying and selling a stock), design an algorithm to find out the maximum profit.Sample Examplegive an example of an array [3,2,3,1,2], return 1SolvingThe popular point is to ask for the following number minus the maximum value of the preceding number, and the last and 0 to take the
