Assuming you've done all your homework, properly identified a stock's price target, and estimated if it is undervalued, don't plan on seeing the stock you bought rise in value straight away. Be patient. It can take time for a stock to trade up to its true value. Analysts who project ...
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。
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...

这道是买股票的最佳时间系列问题中最难最复杂的一道,前面两道Best Time to Buy and Sell Stock和Best Time to Buy and Sell Stock II的思路都非常的简洁明了,算法也很简单。而这道是要求最多交易两次,找到最大利润,还是需要用动态规划Dynamic Programming来解,而这里我们需要两个递推公式来分别更新两个变量local...
122 Best Time to Buy and Sell Stock II 原题地址。这道题是在上题的基础上,然后不限制交易次数,但是每次交易不能同时进行,即买入后要卖出才能进行下一次买入的操作。 第一道题已经把基本的、通用的结果步骤写出来了,我解题的时候大概也是遵循这样的步骤来解,所以第二题就不详细啰嗦的写了。
