Time Limit:10 Sec Memory limit:512 MBDescriptionthe JYY has two strings A and b with a length of N. a twist string s (i,j,k) is made up of a substring consisting of the I character in A to the J character and a substring of the J character in B to the K character. For example, if a= ' XYZ ', b= ' UVW ', then twist the string s (#) = ' XYVW '. Jyy defines a "twisted palindrome" for one of the following situations:a

Given A string s, find the longest palindromic substring in S. Assume that the maximum length of S is 1000. Example: Input: "Babad" Output: "Bab" Note: "ABA" is also a valid answer. Example: Input: "CBBD" Output: "BB" 1. Center Expansion Method O (n*n) You need to consider two cases of palindrome strings being odd and even public class Solution { private int lo, maxlen; Public String Longestpalindrome (string s) { int len = s.length ();

Original question: By definition palindrome was a string which is not the changed when reversed. "MADAM" is a nice example of palindrome. It is an easy job to test whether a given string was a palindrome or not. But it may is not being so easy to generate a palindrome.Here we'll make a palindrome generator which would

We define the "out" of a substring t of sThe present value is the number of occurrences of T in s multiplied by the length of T.

1. Center ExpansionThe Central extension is to take each letter of a given string as a center , extending to both sides, to find the longest child palindrome string. The algorithm complexity is O (n^2). But there are two things to consider:1, like ABA, so the length is odd.2, want to ABBA, so the length is even. The code is as follows:stringFindlongestpalindrome (strings) { Const intLength=s.size (); intMaxlength=0; intstart; for(intI=0; i//an odd

Title DescriptionGiven a string, find the length of its longest palindrome substring.Analysis and SolutionThe easiest way to do this is to enumerate all the substrings and determine whether they are palindrome. This idea seems to be correct at first, but it does a lot of useless work, if a long substring contains another short substring, then the palindrome judgm

Problem Descriptionalice get a string S. She thinks palindrome string is interesting. Now she wanna know how many three tuple (i,j,k) satisfy 1≤i≤j≤ le ng th (s ) , S[i. J] and S[J+1..K] is all palindrome strings. It's easy for her. She wants to know the sum of i*k of all required three tuples. She can ' t solve it. So can I help her? The answer is very large, please output the answer mod 1000000

Description-Problem descriptionOne day, the male Pa taught himself the first style of the law of the Winds: the shadows ... Footwork (Disciple one: Lord of the Church, you are panting.) Wind: You shut up. The key to the Chase is breathing (it's not good to breathe ...) ）。Using the trick is not every step of the pant, but in a specific number of steps panting. In general, the higher the skill, the more sparse the pant. The number of steps to pant matches a specific rule: first if Sushu (disciple

Somehow, he had a strange love for reciting, which prompted him to go to a race of creatures known for his memory. However, he soon found that this did not satisfy his love of reciting heart, but as a powerful Boer, he found such a self-abuse of the way-recite the gene sequence. But this is really too ab

The Manacher algorithm is an algorithm for solving longest palindromic substring (the longest palindrome substring) with time and space complexity of O (n). Palindrome string is a central symmetric string, such as ' ABCBA ', ' ABCCBA '. Then the longest palindrome substring is, by definition, the longest palindrome in

Original: http://www.felix021.com/blog/read.php?2040First, in a very ingenious way, all possible odd/even length palindrome strings are converted to odd lengths: a special symbol is inserted on both sides of each character. For example, Abba becomes #a #b#b#a#, ABA becomes #a #b#a#. In order to further reduce the complexity of the code, you can add another special character at the beginning of the string, so that you do not have to deal with the probl
