Outputthe longest substring with the mentioned property. If There is several such strings you should output the first of them. Sample

In the previous section we learned about queues, which are a first-in, first-out data structure. There is also a LIFO data structure which is called a stack. Stack qualification can only be inserted and deleted at one end. For example, there is a small bucket, the diameter of the bucket can only put a small ball, we now to the small bucket in turn into 2nd, 1th, 3rd ball. If you need to take out the 2nd ball now, then you must first take out the 3rd ball, and then take out the 1th ball, the last
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

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

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

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

One: BackgroundGiven a string, the longest palindrome substring is obtained. For example:
S= "ABCD", the longest palindrome length is 1;
S= "Ababa", the longest palindrome length is 5;
S= "ABCCB", the longest palindrome length is 4, that is, BCCB.
