Given a string s, partition s such that every substring of the partition is a palindrome. Return the minimum cuts needed for a palindrome partitioning of s. For example, given s = “aab”, Return 1 since the palindrome partitioning [“aa”,”b”] could be produced using 1 cut. 思路: ...
(从右往左是为了保证得到的回文子串是最长的)设 s 的长度是 n,算法复杂度是O(n^3),故一定会 TLE 。 换个思路: 试试通过转移状态达到全局最优的 DP:若设 f[ i ] 为 s 的前 i 个字符(s[ : i ])的最少切分次数,那么: f[ i ] 的初始化是 (i - 1),即切分(i - 1)次,把每个字符做为...
leetcode之 Palindrome Partitioning I&II 1Palindrome 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...

Return the minimum cuts needed for a palindrome partitioning of s. For example, given s ="aab", Return 1 since the palindrome partitioning["aa","b"]could be produced using 1 cut. 给定字符串s,分区的每个子字符串都是回文。返回s的回文分区所需的最小切割数。

132. Palindrome Partitioning II DFS不能AC 这题我想像131题那样dfs把所有解找到然后找到需要cut最短的那一个,用一个全局变量保存minCut,每次解出来之后判断是否需要更新。我自己测试了没问题,但提交的时候TLE了。 intminCut;publicintminCut(Strings){if(s==null||s.equals(""))return0;minCut=s.length()...
