[题目] 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 as many transactions as you like (i.e., buy one and sell one share of the stock multiple tim…

问题 假设你有一个数组,其中的第i个元素表示一只股票在第i天的价格. 设计一个算法找出最大的利润值.你可以进行任意多次的交易(即多次的卖出并买入一份股票).你不能在同一时间进行多次交易(即你必须在再次买入股票之前卖出当前的股票) 初始思路 有了在买入与卖出股票的最佳时机III中的分析,这题就很容易得出答案了.像III中那样,我们使用3个变量来纪录利润: Profit currentProfit; Profit maxProfit;int totalProfit; currentProfit表示当…
