str.length(), so code needs to be careful not to pass in numbers outside that range. Note that the last number, str.length(), is one beyond the end of the string. You need this number to fit the "up to but not including" way that substring() works. For the above "Hello" ...

Given a string s, find the longest palindromic substring in s. You may assume that the maximum length of s is 1000. Input: "babad" Output: "bab" Note: "aba" is also a valid answer. 暴力算法就是找到所有substring, 每个都进行isPalindrome的检查。时间复杂度是O(N^3). N^2个substring, ...
