A positive integer is called a palindrome if its representation in the decimal system is the same when read from left to right and from right to left. For a given positive integer K of not more than 1000000 digits, write the value of the smallest pal…
Description 给定k个长度不超过L的01串,求有多少长度为n的01串S满足: 1.该串是回文串 2.该串不存在两个不重叠的子串,在给定的k个串中. 即不存在a<=b<c<=d,S[a,b]是k个串中的一个,S[c,d]是k个串中的一个 (It does not contain two non-overlapped substrings in the given list of K binary strings.) 举个例子,若给定2(k=2)个01串:101和1001 1010…

"not more than 1000000 digits" means an efficient in-place solution is needed. My first solution was string<->int conversion based. It worked for small ints, but got TLE with large numbers. Thanks to http://www.bytehood.com/spoj-the-next-p…

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…
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", "cat"]Ret…
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…
