然后sell往后移, 若prices[sell] < prices[buy],则将buy指向sell当前位置(buy = sell),否则计算当前股票买卖收益,并和之前计算的收益比较,取最大的值。 1//双指针法求股票买卖最佳时机问题23intmaxProfit_doublePtr(vector<int>&prices)4{5intbuy=0,sell=0;6intmaxProfit =0;7for(;sell<prices.size();++...
Say you have an array for which theith element is the price of a given stock on dayi. If you were only permitted to complete at most one transaction (ie, buy one and sell one share of the stock), design an algorithm to find the maximum profit. 思路:变相的求最大子数组,是算法导论上...
用f[i][0]来记录,而f[i]就代表在第i天获得的最大收益是多少。 第二种情况:第i天买了股票,处于冷冻期(无法买入),用f[i][1] 来记录 第三种情况:没有持有股2票,也没有冷冻期(就是可以买入的状态)。用f[i][2]来表示。 我觉得作者这种思路跟我一开始想的没太大区别,只不过我是想f[i][0]可以买...

1. BestTimetoBuyandSellStock 1 给出一个数组,代表第 i 天股票的价格。只能买卖一次,现在设计一个算法, 可以求出最大的profit。 用例:[7,1,5,3,6,4] ==> 5 [5,4,3,2,1] ==> 0 分析与思路 这个没啥好分析的,就是遍历一遍,以O(n)的时间复杂度,记录下买入价格。然后比较得出最大的 profit。
