WebManacher's Algorithm functions similarly to the Z-Algorithm. It determines the longest palindrome centered at each character. Don't Forget! If s [l, r] is a palindrome, then s [l+1, r-1] is as well. Palindromic Tree A Palindromic Tree is a tree-like data structure that behaves similarly to KMP.

In computer science, the longest palindromic substring or longest symmetric factor problem is the problem of finding a maximum-length contiguous substring of a given string that is also a palindrome. For example, the longest palindromic substring of "bananas" is "anana". The longest palindromic substring is not guaranteed to be unique; for example, in the string "abracadabra", there is no palindromic substring with length greater than three, but there are two palindromic s… Web链接：http://acm.hust.edu.cn/vjudge/problem/19667分析：先打个素数表，题目要求从1开始打印，直接把1固定到A[0]位置，打印的时候就 ... trw nelson ncd 66WebProblem:-Given a string s, find out the longest palindromic substring in O(N)using Manacher's algorithm.This video explains the Manacher's Algorithm for find... trw mst300
