best time to Buy and Sell Stock IISay 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 could complete as many transactions as (ie, buy one and sell one share of the stock multiple times). However, engage in multiple transactions for the same time (ie, you must sell the stock before you buy again).The core is to find all the monotonically increasing interval, and then sell to the simplest, whenever there is a pr

time they are used.3.2.3. Using a loop to access an arrayBecause the array uses an ordered number as the index, it is easy to display the contents of the array using a for loop.for ($i =0; $i echo "$products [$i]";Using a simple loop, you can access each element as a very good feature of a numeric index array. You can also use a Foreach loop, which is specifically designed for arrays. Such as:foreach ($products as $current)Echo $current. ‘ ‘;3.3 Arrays using different indexesPHP also supports r

1. Initialization of arrays(1) Create an array with arrayA: $products = array (' tires ', ' oil ', ' Spark plugs ');Array () is actually a language structure, not a function B: Initializing the related array$prices = Array (' Tires ' =>100, ' oil ' =>10, ' Spark plugs ' =>4); To create an array with 3 elements $prices = Array (' tires ' =>100); This is not a way to create an array with 3 elements,$

1. first of all, you must select a machine. Do not change it easily after you select a machine. Otherwise, you will be fooled and will never listen to JS recommendations, that must be the most profitable one. 2. check the agent. This process is difficult for general users to grasp. Don't ask every store. In fact, you should first care about the brand in your city (assuming the X brand here) the general agent information can be found on the X brand website or on the phone number 800. You can ask

Conversely, the downward trend refers to the development of the market, the wave-like trend of the low point continued to decline, and rebound highs can not travel through the previous wave of highs. For the ascending trend, the length of the ascending wave exceeds the descending wave. In a clear upward trend, prices are mostly in the vicinity of the highest price in the plate. Conversely, in a clear downward trend, the closing price mo

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 track Maximu M profit for Transcations after
