LeetCode:
Palindrome
Partitioning II
思路:这个题目不能用深度搜索来进行求解,会超时,参考了网上讨论的DP算法,用一个ret[i]表示从i到字符末尾需要切断的次数,则ret[i]=min(ret[i],ret[j]+1),j=i+1,...,n。ret[i]都初始化为n-i-1表示切成单个字符需要的次数。为了不重复计算i到j是否为回文字符串,可以用一个标记数组dp[i][j]来进行表示子串s(i,...j)是否为回文串,如果s[i]=

题意:插入最少的字母使其变成回文串。只要将原字符串和其倒过来的字符串求最长公共字符串就OK了。还要考虑就是内存过大的问题,我是将5000*5000变成2*5000的数组来解决的,只要每次操作之后将把数组都往上移动一层,那么始终只使用2层的一维数组。这是基于使用完那层的数组就不使用,并不影响后面的操作。#include #include #include usingnamespacestd; int
