原题 思路: 状态转移 出售股票的状态,最大利润有两种可能. 一,和昨天一样不动:二,昨天持有的股票今天卖掉. sell[i] = max(sell[i-1],buy[i-1] + prices[i]); 购买股票的状态,最大利润有两种可能. 一,和昨天一样不动:二,两天前出售,今天购买. bdp[i] = Math.max(bdp[i-1],sell[i-2] - prices[i]); class Solution { public: int maxProfit(vector<int> &…

题目描述 给定一个整数数组,其中第 i 个元素代表了第 i 天的股票价格 .​ 设计一个算法计算出最大利润.在满足以下约束条件下,你可以尽可能地完成更多的交易(多次买卖一支股票): 你不能同时参与多笔交易(你必须在再次购买前出售掉之前的股票). 卖出股票后,你无法在第二天买入股票 (即冷冻期为 1 天). 示例: 输入: [1,2,3,0,2] 输出: 3 解释: 对应的交易状态为: [买入, 卖出, 冷冻期, 买入, 卖出] 解决方案1 可以通过一个状态转换图,来解决. 定义状态 s0 : 没…
