题目大意: 祖玛游戏. 给你一个01串,你可以往里面加一些0或1,如果连续的0或1超过3个,那么就可以消去.问消去所有的珠子至少要加几个珠子. 思路: 区间DP. 首先把原来的01串,改成存储连续的同种颜色的珠子有几个. 考虑只有一种珠子时,f[i][j]=3-a[i]: 若当前区间有多种颜色的珠子,分为以下几种情况: 1.由两个区间合并而来,f[i][j]=std::min(f[i][j],f[i][k]+f[k+1][j]): 2.如果当前区间内有奇数个连续的同色珠子块,又分为以下2种情况:…

Codeforces Round #336 (Div. 2) D. Zuma 题意:输入一个字符串:每次消去一个回文串,问最少消去的次数为多少? 思路:一般对于可以从中间操作的,一般看成是从头开始(因为只需要考虑一边),当考虑最左边的数时,有多少中消去方法?每种消去方法对结果的贡献又是多少?同时结果的区间又是怎么变化?这就是dp式子: 1.当单独消去这个元素时,dp[l][r] = 1 + dp[l+1][r]; 2.当存在一个k,l< k <= r,使得c[l] == c[k]时,可以认为在…
