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. 如果只允许你完成一次交易(即买入并卖出股票一次),设计一个找出最大利润的算法. 初始思路 和122一样,基于买入与卖出股票的最佳时机III中的分析很容易得出答案.由于只允许进行一次交易,本题更加简单,我们只需按III中的方法不断更新最大利润即可. class Solution { public: int maxProfit(std::vector<int> &prices) { return CaculateProf…
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…
