We see that S[i] on day i can be easily computed if we know the closest day preceding i, such that the price is greater than on that day than the price on the day i. code. The stock span problem is a financial problem where we have a series of n daily price quotes for a stock and we need to calculate span of stockâ s price for all n days. http://crypto.cs.mcgill.ca/~crepeau/CS250/2004/Stack-I.pdf. Your algorithms have become so good at predicting the market that can predict the share price of Wooden Orange Toothpicks Inc. Dismiss Join GitHub today. generate link and share the link here. When we go from day i-1 to i, we pop the days when the price of the stock was less than or equal to price[i] and then push the value of day i back into the stack. Improve your coding skills with our library of 300+ challenges and prepare for coding interviews with content from leading technology companies. You are given an array prices where prices[i] is the price of a given stock on the i th day.. You want to maximize your profit by choosing a single day to buy one stock and choosing a different day in the future to sell that stock..

Return the maximum profit you can achieve from this transaction.If you cannot achieve any profit, return 0.. The span Si of the stock’s price on a given day i is defined as the maximum number of consecutive days just before the given day, for which the price of the stock on the current day is less than or equal to its price on the given day. For example, if the given array is {100, 180, 260, 310, 40, 535, 695}, the maximum profit can earned by buying on day 0, selling on day 3. View on GitHub myleetcode. There are plants in a garden.
