Gram. Inputthe input consists of a single line, which contains a string of Latin alphabet letters (no other characters would appe AR in the string). String length would not exceed characters. Outputthe longest substring with the mentioned property. If There is several such strings you should output the first of them.

PS. This paste most of the text and code from the Internet, I just collated the nextS= "c A b a" then s ' = "a B a C", in which case the longest common substring of s and S ' is ABA. No errors.But when s= "Abacdfgdcaba", then S ' = "Abacdgfdcaba". So the longest common substring of s and S ' is ABACD. It is obvious that ABACD is not the longest palindrome string of s, it is not even a palindrome.It is now clear why the longest

DescribeSmall hi and small ho is a pair of good friends, born in the information society, they have a great interest in programming, they agreed to help each other, in the programming of learning along the road together.On this day, they encountered a string of strings, so little hi to small ho raised the classic question: "Little ho, you can find each of them in these strings each of the longest palindrome string it?" " Little Ho asked curiously, "W

1 Palindrome PartitioningProblem Source: Palindrome PartitioningThe problem is simply given a string, dividing the string into multiple parts, satisfying each part as a palindrome, and outputting all possible scenarios.The difficulty of the problem is relatively large, it is likely that the first encounter without thinking, it is normal. Below we analyze a little

Turn from blog: www.cnblogs.com/mickole/articles/3578298.html Title: (Alternative topics can be found in the Pat ladder exercises, of course, the problem N3 can be too) A string of length n (n Large), which is the longest palindrome in the string. (Baidu 2014 School Recruit written questions) The topic pointed out "N is very big", that is, we do not want to go through the way to find this string, I think of a solution, time complexity should not be h

Manacher algorithm (Http://www.jianshu.com/p/799bc53d4e3d)For a long string, the time complexity of O (n^2) is unacceptable. Can We do better?Let's take a look at the flaw in Solution 2 .1) due to the odd-even nature of palindrome string length, the symmetry axis position of different properties is caused.Solution 2To handle the two cases separately, 2) Many substrings are repeatedly accessed, resulting in poor time efficiency.Defect 2) can be through

This article is introduced to Manacher in detail, and it is easy to read, the original is transferred from: http://blog.csdn.net/pi9nc/article/details/9251455First, the problem descriptionGiven a known string str[], now want to find a longest palindrome substring (positive and backward sequential reads) within the time complexity of O (n).Manacher first found that the time complexity of O (n) can be used to solve this problem, so this method is called

Given A stringS, find the longest palindromic substring inS. Assume that maximum length ofSis, and there exists one unique longest palindromic substring.The examiner of the face DP problem is a psychopath.。 (Spit Groove)Seems to be easy out of a palindrome problem, then today carefully analyze the practice of DP!!In order to solve my problem of DP problems to the broken heart feeling of slag. If there is an error please indicate ~First of all. Take th

"Manacher algorithm"This algorithm is used to find the longest palindrome substring in a string.If you take a violent solution to the longest palindrome substring problem, there are probably two ways to think about it: 1. Traverse out all substrings to find the longest palindrome 2. From each character as the center, spread to both sides to see if a

Output palindrome string public static void Maxhuiwen (string s) {//Length of the storage string int. = S.length (); Store the longest palindrome string maxstring = ""; Traverses all substrings for the current string for (int i

In computer science, the problem with the longest palindrome or longest symmetric factor is to find one of the longest contiguous substrings in a string, which must be a palindrome. For example "Banana" the longest palindrome substring is "Anana". The longest palindrome string is not guaranteed to be unique, for exampl

Transmission Door Test instructionsTo the string s, find the logarithm of all the palindrome strings that intersect in S.

backgroundRecently began to study the algorithm, so in Leetcode do algorithm problem, the fifth question longest palindromic Substring is about palindrome string.What is a back text stringA palindrome string is a string that is reversed before and after the string is the same as the string. For example: A,aaaa,aba,abba ...Longest palindrome substringRequiring the

First, describeThe definition of palindrome:"palindrome number" is the same integer that reads backwards. If the odd number of numbers: 98789, the number is 98789, the reading is 98789, even the number of the number 3223 is a palindrome number. We are today to expand the number of palindrome to a combination of letters

Given a string S, find the longest palindromic substring in s. The maximum length of S is assume, and there exists one unique longest palindromic substring.1, the violent solution.The simplest algorithm for calculating the longest string of strings is to enumerate each substring of the string, and to determine whether the substring is a palindrome, and the time complexity of the algorithm is O (n^3) , which is obviously unsatisfactory.2. The midpoint
