这道题相比之前一道类似的题122. Best Time to Buy and Sell Stock II的区别就是加上了一个cooldown的限制条件,就是卖完股票的接下来一天不能再接着买,至少需要等待一天之后才能买。中间不能参与交易的那些日期就称为所谓的“cooldown”时期,现在问最大的收益是多少?
121. Best Time to Buy and Sell Stock 121 这个比较简单,大致思想: 1.如果sale-buy<=0,则该价格适合买入。 2.否则判断该价格卖出的价格是否最好。 代码如下: publicintmaxProfit(int[]prices){if(prices==null||prices.length==0){return0;}intres=0;intbuy=prices[0];for(inti=1;i<prices.length;i...
Say you have an array for which the ith element is the price of a given stock on day i. If you were only permitted to complete at most one transaction (i.e., buy one and sell one share of the stock), design an algorithm to find the maximum profit. ...
给定一个数组prices,它的第i个元素prices[i]表示一支给定股票第i天的价格。 你只能选择某一天买入这只股票,并选择在未来的某一个不同的日子卖出该股票。设计一个算法来计算你所能获取的最大利润。 返回你可以从这笔交易中获取的最大利润。如果你不能获取任何利润,返回0。
