or we choose to sell the stock: in order to sell the stock on day j, we have to bought it on day[0~j-1] since we can’t sure which day is the day to buy in, so we have to iterate through every day to get the maximum so we have to get max(dp[i-1][t-1] + prices[j...

121 Best Time to Buy and Sell Stock 原题地址。题目的意思大概是,给你一个股票的每天价格数组prices,你在只能进行一次操作(即一次买入和一次卖出)的限制下,求最大的收益。比如每天的价格为[7, 1, 5, 3, 6, 4],那么最大收益就是1的时候买入,6的时候卖出,这样就能得到最大收益5。
输入:prices = [7,6,4,3,1]输出:0解释:在这种情况下, 没有交易完成, 所以最大利润为 0。 提示: 1 <= prices.length <= 105 0 <= prices[i] <= 104 题目难度:简单 通过次数:1.6M 提交次数:2.8M 贡献者:LeetCode 相关标签 数组动态规划 ...
