题目描述 已知一个数组,第i个元素表示第i天股票的价格,你只能进行一次交易(买卖各一次),设计算法找出最大收益 测试样例 Input: [7, 1, 5, 3, 6, 4] Output: 5 最大收益 = 6-1 = 5 (不是7-1 = 6,因为先买后卖,7买,1买亏了6) Input: [7, 6, 4, 3, 1] Output: 0 最大收益为0 详细分析 初看非常简单,遍历数组,每次选择一个元素,找到这个元素后面的数组的最大值,计算差值,和当前最大收益比较即可,就像这样: [7,1,…

由于题意太长,请自己翻译,很容易懂的. 做法:从前向后遍历数组,记录当前出现过的最低价格,作为买入价格,并计算以当天价格出售的收益,作为可能的最大收益,整个遍历过程中,出现过的最大收益就是所求.动态规划的思路下次有空写个专题 class Solution { public: int maxProfit(vector<int>& prices) { ) ; ; ]; ; i < prices.size(); i++) { curMin = min(curMin, prices[i]…
