很久没写博客了,越来越懒了,这次还是要分享LeetCode上一道动态规划的题目,和之前的Ballon Boom那个题(我记得是这个标题吧...)差不多,都是对一个数组的区间进行枚举的题,而且涉及到区间和子区间取值的问题,不过那个题和矩阵链乘法基本是一样的, 这个题的话相对来说更难一点,因为这个题需要对一个三维的dp数组进行维护,最后一个维度的考虑是比较难的.直接提供代码,思路以后有时间再补: class Solution { public int removeBoxes(int[] boxes)…

Given several boxes with different colors represented by different positive numbers. You may experience several rounds to remove boxes until there is no box left. Each time you can choose some continuous boxes with the same color (composed of k boxes…

给定一些不同颜色的盒子,以不同的正整数表示.消去连续相同颜色的盒子,直到全部消除完毕为止.每一次消去可以得到k * k分(k为消去盒子的个数, k  >= 1).计算可以得到的最大得分.注意:盒子的数量n不超过100. 详见:https://leetcode.com/problems/remove-boxes/description/ C++: class Solution { public: int removeBoxes(vector<int>& boxes) { int n…

Leetcode546 给定一个整数序列,每次删除其中连续相等的子序列,得分为序列长度的平方 求最高得分. dp方程如下: memo[l][r][k] = max(memo[l][r][k], dfs(boxes,memo,l,i,k+1) + dfs(boxes,memo,i+1,r-1,0)); 意思是在序列的l-r部分后接k长度的 r值序列 所能得到的最大得分. 代码很简单 class Solution { public: int removeBoxes(vector<int>&…

题目链接: https://leetcode.com/problems/remove-boxes/description/ 问题描述 若干个有序排列的box和它们的颜色,每次可以移除若干个连续的颜色相同的box,且得分为移除个数的平方,求最大的得分. n不超过100. 输入 输入n个箱子的颜色. 输出 输出最大的得分. 样例输入 1, 3, 2, 2, 2, 3, 4, 3, 1 样例输出 23 题解 令dp[l][r][k]表示前面有k个和box[l]同颜色的要和box[l]一起消除,现在考虑…
