Longest Palindromic Substring最长回文字符串算法 从leetcode上面看到了一道非常有意思的算法题,求一个字符串的最长回文,回文的意思就是无论你是从左读还是从右读都是相同的,她有两种情况:奇数对称和偶数对称。 比如 ,字符串: "abdgdbpmn&... leetCode(longest-palindromic-substring)-最长回文字串 ...
简介:需求:Given a string S, find the longest palindromic substring in S. You may assume that the maximum length of S is 1000, and there exists one unique longest palindromic substring. 如果一个字符串从左向右写和从右向左写是一样的,这样的字符串就叫做palindromic string 判断回文数,中间开花。
