Given a string s, partition s such that every substring of the partition is a palindrome. Return all possible palindrome partitioning of s. Example: Input: "aab" Output: [ ["aa","b"], ["a","a","b"…

Given a string s, return all the palindromic permutations (without duplicates) of it. Return an empty list if no palindromic permutation could be form. For example: Given s = "aabb", return ["abba", "baab"]. Given s = "a…

1. Description Given a list of unique words. Find all pairs of distinct indices (i, j) in the given list, so that the concatenation of the two words, i.e. words[i] + words[j] is a palindrome. Example 1: Given words = ["bat", "tab", &qu…

题目如下: 解题思路:对于任意一个word,要找出在wordlist中是否存在与之能组成回文的其他words,有两种思路.一是遍历wordlist:二是对word本身进行分析,找出能组成回文的words,并判断是否存在于wordlist中.显然,第二种思路比较的次数要少很多.怎么找出能组成回文的words呢?只要把后面的字符依次往前复制,并判断是否为回文,直到全部字符复制完成为止,这就能得到所有能与之组成回文的words.以abcd作为前缀为例,首先把d复制到abcd前面得到dabcd,接下来依…

Given a string which consists of lowercase or uppercase letters, find the length of the longest palindromes that can be built with those letters. This is case sensitive, for example "Aa" is not considered a palindrome here. Note: Assume the leng…
