[ 问题: ] Given a string, determine if it is a palindrome, considering only alphanumeric characters and ignoring cases. 直译:给你一个字符串, 判定它是否是回文(仅仅统计字母.数字.其它字符请忽略). For example, "A man, a plan, a canal: Panama" is a palindrome. "race a car"…
翻译 给定一个字符串.确定它是否是回文的,仅仅考虑当中的数字和字符并忽略其它. 比如. "A man, a plan, a canal: Panama" 是回文的. "race a car" 不是回文的 批注: 你是否考虑了字符串可能为空?这样的面试的时候是一个好问题. 对于这问题的意图,我们定义空字符串是回文的. 原文 Given a string, determine if it is a palindrome, considering only alphanu…

Determine whether an integer is a palindrome. Do this without extra space. click to show spoilers. Some hints: Could negative integers be palindromes? (ie, -1) If you are thinking of converting the integer to string, note the restriction of using ext…
Determine whether an integer is a palindrome. An integer is a palindrome when it reads the same backward as forward. Example 1: Input: 121 Output: true Example 2: Input: -121 Output: false Explanation: From left to right, it reads -121. From right to…
Given a string which consists of lowercase or uppercase letters, find the length of the longest palindromes that can be built with those letters. This is case sensitive, for example "Aa" is not considered a palindrome here. Note:Assume the lengt…

给定一个字符串,确定它是否是回文,只考虑字母数字字符和忽略大小写.例如:"A man, a plan, a canal: Panama" 是回文字符串."race a car" 不是回文字符串.注意:你有考虑过这个字符串可能是空的吗? 在面试中这是一个很好的问题.针对此题目,我们将空字符串定义为有效的回文字符串.详见:https://leetcode.com/problems/valid-palindrome/description/ Java实现: class S…
问题描述 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. 所谓回文字符串,就是一个字符串,从左到右读和从右到左读是完全一样的.比如"a" , "aaabbaaa" 之前…
