I. Title DescriptionSay you had an array for which the i-th 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.Two. Topic analysisThe title means to enter an array that represents a stock price per day, and the first i element represents i the stock price of the day, allowing only one

After understanding that the previous question is the sum of the largest continuous sub-arrays, this question is much simpler. If it is less than 0, do not add it. Public class solution {public int maxprofit (INT [] prices) {If (prices. length Best time to buy and stock Stock II

Say you have an array for which the ith element is the price of a given stock on day I. Design an algorithm to find the maximum profit. You may complete at most two transactions. Note:You may not engage in multiple transactions at the same time (ie, you must encrypt the stock before you buy again ).1: special case; 2: traverse two numbers from front to back and from back to front; 3: During traversal, save

Algorithm:Scan through the array, keep finding1. Prices[i] with the condition:prices[i] 2. Prices[i] with the condition:prices[i] > prices[i+1], or at the end of a ascending trend, treat it as selling PO IntKeeping till reach the end of the array;　　Note:1. If a buying point is recorded and does reach the end, then must exist a selling point after it (must exist some point L Arger than buying point)2. If reach the end when finding the buying point, then stop and finish the whole programe.best

It is easy to know that you are seeking a continuous maximum number of sub-arrays. But note the boundary conditions, assuming the sum of the maximum subarray of 0, then do not trade, return 0.public class Solution {public int maxprofit (int[] prices) { if (Prices.length Leetcode-best time to Buy and Sell Stock

Traverse the price vector, add up the profit for each period of the ascent, and remember to calculate the last profit at the end. Class Solution { //Add up profit for each period of ascent //Minval: Trough value //maxval: Peak //Profit: Profit public: int Maxprofit ( Vector profit + = Maxval-minval; Minval = Maxval = Prices[i]; } If up, change the peak else{ maxval = prices[i]; } } Finall
