https://vjudge.net/problem/POJ-2385 猛刷简单dp的第一天的第一题. 状态:dp[i][j]表示第i秒移动j次所得的最大苹果数.关键要想到移动j次,根据j的奇偶判断人在哪里. 想了挺久的,最后还是参考了一篇和自己思路最近的代码https://blog.csdn.net/hellohelloc/article/details/52050207 我比他缺少的是特判dp[i][0]的状态,后面的一切都以此为基础的. #include<iostream> #inclu…

dp题: 1.写状态转移方程; 2.考虑初始化边界,有意义的赋定值.还没计算的赋边界值: 3.怎么写代码自底向上计算最优值 今天做了几个基础dp,所有是dp方程写对可是初始化以及计算写错 先是poj 1651 事实上就是个赤裸裸的矩阵连乘.dp方程非常easy写出 dp[i][j]=min(dp[i][k]+dp[k+1][j]+r[i]*c[k]*c[j],dp[i][j]); 先贴两个个二逼的代码,mark下自己多么的二逼: 二逼一:在计算的时候使用了还没有算出来的值,模拟下就知道第一重循环…
