{ "data": { "question": { "questionId": "714", "questionFrontendId": "714", "categoryTitle": "Algorithms", "boundTopicId": 1162, "title": "Best Time to Buy and Sell Stock with Transaction Fee", "titleSlug": "best-time-to-buy-and-sell-stock-with-transaction-fee", "content": "
You are given an array prices
where prices[i]
is the price of a given stock on the ith
day, and an integer fee
representing a transaction fee.
Find the maximum profit you can achieve. You may complete as many transactions as you like, but you need to pay the transaction fee for each transaction.
\n\nNote: You may not engage in multiple transactions simultaneously (i.e., you must sell the stock before you buy again).
\n\n\n
Example 1:
\n\n\nInput: prices = [1,3,2,8,4,9], fee = 2\nOutput: 8\nExplanation: The maximum profit can be achieved by:\n- Buying at prices[0] = 1\n- Selling at prices[3] = 8\n- Buying at prices[4] = 4\n- Selling at prices[5] = 9\nThe total profit is ((8 - 1) - 2) + ((9 - 4) - 2) = 8.\n\n\n
Example 2:
\n\n\nInput: prices = [1,3,7,5,10,3], fee = 3\nOutput: 6\n\n\n
\n
Constraints:
\n\n1 <= prices.length <= 5 * 104
1 <= prices[i] < 5 * 104
0 <= fee < 5 * 104
给定一个整数数组 prices
,其中 prices[i]
表示第 i
天的股票价格 ;整数 fee
代表了交易股票的手续费用。
你可以无限次地完成交易,但是你每笔交易都需要付手续费。如果你已经购买了一个股票,在卖出它之前你就不能再继续购买股票了。
\n\n返回获得利润的最大值。
\n\n注意:这里的一笔交易指买入持有并卖出股票的整个过程,每笔交易你只需要为支付一次手续费。
\n\n\n\n
示例 1:
\n\n\n输入:prices = [1, 3, 2, 8, 4, 9], fee = 2\n输出:8\n解释:能够达到的最大利润: \n在此处买入 prices[0] = 1\n在此处卖出 prices[3] = 8\n在此处买入 prices[4] = 4\n在此处卖出 prices[5] = 9\n总利润: ((8 - 1) - 2) + ((9 - 4) - 2) = 8\n\n
示例 2:
\n\n\n输入:prices = [1,3,7,5,10,3], fee = 3\n输出:6\n\n\n
\n\n
提示:
\n\n1 <= prices.length <= 5 * 104
1 <= prices[i] < 5 * 104
0 <= fee < 5 * 104
