Valid Palindrome II

题目描述：给定非空串S，是否能在最多删除一个字符的条件下使得原串变为回文串。如：Input:"abca"Output:TrueExplanation:Youcoulddeletethecharacter'c'.分析：开始的想法是遍历字符串，删除每个字符看是否构成回文串，以及原本是否是回文串。复杂度O(n^2)，超时。这种方法会重复遍历很多次已判断过的情况，降低复杂度就要通过一次遍历完成判断，时间复

从Shortest Palindrome@LeetCode理解KMP

ShortestPalindrome用Java暴力是可以过的，思路也很简单：补充完成之后的回文串中心必定在原字符串中，所以原字符串以第一个字符为起点必然存在至少一个回文串（长度可以为1），那么任务就变为找到原字符串中以第一个字符为起点最长的回文串
