As a programmer, it is better to sell walnuts. in January, the sales volume of the store in a single day exceeded 30 thousand.
In November 2013, I resigned from my role as a php engineer. in the face of the transformation of my life, I felt particularly uneasy. Although I have accumulated some funds in my 4-year career competition, I felt very helpless at the beginning of my career in Guangzhou's high-cost life. in order to keep the proje

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.Ideas:1, the topic requests most trades two times, if only trades once, the question is "best time to Buy and Sell the Stock";If the transaction must be traded two times, the first transaction is sold on the I trading day, then the problem degrades into the maximum benefit of 0 to I

QuestionSay 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).SolutionThis problem can is solved by "divide and conquer". We can use Left[i] array to track maximum profit for transactions before I (including i), and Right[i + 1] to
