You are in most of the transactions.Note:Engage in multiple transactions on the same time (ie, you must sell the stock before you buy again).Let's see if it's a trick or a big profit, but you're allowed to trade twice or you have to sell it before you buy it.No idea.

Android Application Development: Dialog uses 123 and androiddialogIntroduction In Android development, we usually use Dialog in many cases, that is, the pop-up box. If a logon dialog box is displayed, you need to confirm the operation again. This article describes how to correctly use the Dialog during Android development. Design Philosophy of Dialog Dialog is a Dialog box that prompts you to confirm the next operation (this operation is not execute

Say you has an array for which the i-th element is the price of a given-stock on day I.Design an algorithm to find the maximum profit. You are in most of the transactions.Note:Engage in multiple transactions on the same time (ie, you must sell the stock before you buy again).The extension of the previous question, the requirement is to buy and sell only two times, and then find the maximum profit.With dynamic planning, the front and back are calculated once, and then the results are calculated.

Then, we give some titles, find all the keywords in the titles, and sort the titles in the Lexicographic Order of these keywords. Note two points: the same keyword appears in different titles, and the title appears in the front of the input (as shown in the sample data, and multimap does the same ); the same keyword appears multiple times in a title, and the keyword is in the front of the previous position
