Interview question for Intern in Santa Clara, CA.parallel programming of maximum single-sell profit algorithm with pthread/openmp Best Cities for Jobs 2020 NEW! For example, price = [23171, 21015, 21123, 21366, 21013, 21367] then maximum single sell profit will be price[5] – price[4] = 21367 – 21013 = 354. INPUT : arr[] = {4, 9, 7, 15, 20} OUTPUT : Buy on day 0 and sell on day 1 Buy on day 2 and sell on day 4. Explanation for the article: http://www.geeksforgeeks.org/stock-buy-sell/ This video is contributed by Harshit Jain. Maximum single-sell profit. Login {} [+] {} [+] … Find Buy/Sell Prices in Array of Stock Values to Maximize Profit - Given a single array of real values, each of which represents the stock value of a company after an arbitrary period of time, find the best buy price and its corresponding best sell price . What is the optimal algorithm for the game 2048? Algorithm The problem is to find the maximum profit we can make. 20x = 1500 x = 75. Sample 2: Input: [7, 9, 5, 6, 3, 2] Output: If we buy a stock at 7 and sell at 9 then profit is maximum (2). Note that you cannot sell a stock before you buy one. We can solve it by some modification to Kadane’s Algorithm described here in my previous post. Write an algorithm to maximize the profit in single buy and sell. Maximum Single Sell Profit algorithm (Java) 3. Maximizing profit for given stock quotes. Example: int[] prices = {200, 500, 1000, 700, 30, 400, 900, 400, 50}; Output: Maximum Profit: 870, buy date index: 4, sell date index: 6 Approach 1: Brute Force. 1931. Kadane’s Algorithm I'm wondering if there are possible improvements for logic correctness. Maximum profit by buying and selling a share exactly k times. Use two nested loops. So answer is 0. 0. In this tutorial, we explained the problem of finding the maximum single-sell profit from an array of prices. Example 1: Input: [7,1,5,3,6,4] Output: 5 Explanation: Buy on day 2 (price = 1) and sell on day 5 (price = 6), profit = 6-1 = 5. Output: If we buy a stock at 60 and sell at 125 then profit is maximum (65). Here is my code that I tested for basic test cases. Example. Image Processing: Algorithm Improvement for 'Coca-Cola Can' Recognition. Then, we showed how to improve it to obtain a dynamic programming solution. 0. For example: Stock Buy Sell to Maximize Profit Algorithm Lets … Step 4: Use algebra to find how many units are produced from the equation you wrote in Step 3. Its time complexity is O(n). Given an array of integers representing stock price on a single day, find max profit that can be earned by 1 transaction. If you were only permitted to complete at most one transaction (i.e., buy one and sell one share of the stock), design an algorithm to find the maximum profit. Step 2: Find the derivative of the profit equation (here’s a list of common derivatives).For example, the profit equation -10x 2 + 1500x – 2000 becomes -20x + 1500.. Sample 3: Input: [6, 5, 4, 3, 2, 1] Output: Prices are in decreasing order so there will be no profit as stock prices goes on decreasing. Given an array which contains stock price on each day, find the maximum profit that you can make by buying and selling in those days. Jobs Here, we can buy and sell multiple times but only after selling a stock you can buy another stock. In the beginning, we presented the naive approach. 1686. 38. I am trying to use the OpenMP API (or pthreads) to parallelize the following code. You are allowed to buy and sell the stock only once. So you need to find a pair (buyDay,sellDay) where buyDay < = sellDay and it should maximize the profit. Step 3: Set the equation equal to zero:-20x + 1500 = 0.
