题目描述 给定一个字符串 s,将 s 分割成一些子串,使每个子串都是回文串. 返回符合要求的最少分割次数. 示例: 输入: "aab" 输出: 1 解释: 进行一次分割就可将 s 分割成 ["aa","b"] 这样两个回文子串. 解题思路 动态规划思想.从最后一个字符开始向前遍历,每次判断以当前字符为首字母依次到最后字符的子字符串是否为回文串,若是则更新包含当前回文串的最小回文串数.具体想法可参考leetcode之 Palindrome Part…

1 Palindrome Partitioning 问题来源:Palindrome Partitioning 该问题简单来说就是给定一个字符串,将字符串分成多个部分,满足每一部分都是回文串,请输出所有可能的情况. 该问题的难度比较大,很可能第一次遇到没有思路,这很正常.下面我们一点点分析,逐步理清思路.先不考虑所有的情况,针对一个符合条件的划分,每一部分都是一个回文子串,而且各部分的长度不固定.也即每一部分都是原始字符串的一个子串,且满足回文条件.所有的划分都满足上述条件,所以这就启发我们首先判…

Palindrome Partitioning II 这个题意思挺好理解,提供一个字符串s,将s分割成多个子串,这些字串都是回文,要求输出分割的最小次数. Example:Input: "aab"Output: 1Explanation: The palindrome partitioning ["aa","b"] could be produced using 1 cut. 状态:这个题的状态也非常好理解,dp[i]表示将s[0..i]分割成回…

leetcode132. Palindrome Partitioning II 题意: 给定一个字符串s,分区使分区的每个子字符串都是回文. 返回对于s的回文分割所需的最小削减. 例如,给定s ="aab", 返回1,因为可以使用1切割生成回文分割["aa","b"]. 思路: 一开始我用dfs + 贪心来做,找到最长的回文,然后拆掉继续dfs,然后最后一个测试样例过不了,不是复杂度的问题,是算法本身有问题. 看了别人的思路,是用dp来做的,设D…

参考:http://www.cppblog.com/wicbnu/archive/2013/03/18/198565.html 我太喜欢用dfs和回溯法了,但是这些暴力的方法加上剪枝之后复杂度依然是很高,显然不能达到题目的要求. 这个时候应该考虑动态规划,并且要复杂度尽量接近O(n^2)的算法. 下面这个方法更加简洁:自长到短找到回文串后,往后dfs,并记录递归深度表示并更新最小划分数.http://fisherlei.blogspot.com/2013/03/leetcode-palindro…
