题目 Say you have an array for which the ith element is the price of a given stock on day i. Design an algorithm to find the maximum profit. You may complete as many transactions as you like (ie, buy one and sell one share of the stock multiple times).…

这是悦乐书的第173次更新,第175篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第32题(顺位题号是122).假设有一个数组,其中第i个元素是第i天给定股票的价格.设计算法以找到最大利润.可以根据需要完成尽可能多的交易(即,多次买入并卖出一股股票). 注意:不能同时进行多笔交易(即,您必须在再次购买之前卖出股票). 例如: 输入:[7,1,5,3,6,4] 输出:7 说明:在第2天买入(价格= 1)并在第3天卖出(价格= 5),利润= 5-1 = 4.然后在第4天…
