Say you has an array for which the i-th element is the price of a given-stock on day I.If you were-permitted-to-complete at most one transaction (ie, buy one and sell one share of the stock), design an AL Gorithm to find the maximum profit.Example 1:Input: [7, 1, 5, 3, 6, 4]output:5max. difference = 6-1 = 5 (Not 7-1 = 6, as selling-price needs-be-larger than buying price)Example 2:Input: [7, 6, 4, 3, 1]output:0in this case, no transaction was done, i.e. Max Profit = 0.Subscribe to see which comp

First: Test instructions is the stock price of a stock in an array. The first I is the price of the first day. The most profitable. Allowed to buy and sell onceThe problem is to ask for the maximum difference. You can record the minimum value and then, based on the minimum value, find the current maximum difference. Public classSolution { Public intMaxprofit (int[] prices) { if(prices.length==0| | Prices.length==1) { return0;

First, the topic1, examining2. AnalysisGive an array so that you have val1 to buy, and then sell with Val2, to get the most profit.Second, the answer1, Ideas:Method One,The minimum value that is recorded to the current position with the Traverse min;Max records the maximum profit that is obtained when the price of the current array value is sold. Public intMaxprofit (int[] prices) { if(Prices.length ) return0; intMin =

new buyers. If there is a way to sell expensive items to those who are willing to buy at a high price, or to those who just want to buy at a lower price, it would be nice. The policy of giving up uniform pricing and setting different prices for different consumers is called "price discrimination ".For sellers, the most perfect situation is to have the ability to read from every buyer, to know the highest price that everyone is willing to pay, and sel

Say you has an array for which the i-th element is the price of a given-stock on day I.If you were-permitted-to-complete at most one transaction (ie, buy one and sell one share of the stock), design an AL Gorithm to find the maximum profit.The subject only needs to be traversed once, maintaining two pointers, one pointing to the lowest price before I, one pointing to the lowest price, and the highest price before I, if prices[i] is higher than high, t

Say you had an array for which the ith element was the price of a given stock on day I.If you were-permitted-to-complete at most one transaction (ie, buy one and sell one share of the stock), design an AL Gorithm to find the maximum profit.This is very intuitive, the direct difference between the highest value on the line, the start of the tle once, because the use of O (n^2)method, and later found O (n) to be able.The first code:classSolution { Public:intMaxprofit ( vectorint>

Note:you engage in multiple transactions at the same time (ie, you must sell the stock before you buy again).The problem was done at best time to Buy and Sell Stock III, which only took K 2.The recursive type remainsLocal[i][j]=max (Global[i-1][j-1]+max (diff,0), Local[i-1][j]+diff),Global[i][j]=max (Local[i][j],global[i-1][j])Note that there is a big cas

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
