这是这个系列题目的第四个,题目大意和之前的差不多,但是这次提供最多k次的操作,操作还是不能同时操作即必须结束前一个操作才能进行后一个操作. 状态比较好理解,就是题目要求的缩小版,dp[k][i]表示进行到第i天时最多k次操作能得到的最大利益,但是要注意最后一次操作不一定时第i天完成的.状态转移方程:dp[k][i] = max(dp[k][i-1],dp[k-1][j]+prices[i]-prices[j]) (0<=j<=i)比如现在正在考虑dp[k][i],选择有两种,一是第i天不操作,…

https://leetcode.com/problems/best-time-to-buy-and-sell-stock-iv/description/ [题意] 给定n天股市的票价,最多交易k次,问最大盈利是多少,手上不能同时持有两支股票. [思路] 考虑加入当天买当天卖这种情况,问题转换为n天总共交易k次(不是最多),因为后一次的买一定在前一次卖之后,所以需要dp[i][j]表示前i天交易j次且最后一次交易在第i天的最大利润.则 dp[i][j]=max(a[i]-a[k]+global[…
