然后就是从两头开始判断,只要是不相等就返回false,如果不用先有的函数,那么实现一个判断是否为字母数字的函数和一个大小写转换的函数即可,直接看代码: 1publicclassSolution {2publicbooleanisPalindrome(String s) {3intlen=s.replaceAll("[^a-zA-Z0-9]","").length();4String tmp=s.replaceAll("[^a-zA-...
Given a string s, return true if it is a palindrome, or false otherwise. 英文版地址 leetcode.com/problems/v 中文版描述 给定一个字符串 s ,验证 s 是否是 回文串 ,只考虑字母和数字字符,可以忽略字母的大小写。本题中,将空字符串定义为有效的 回文串 。 示例1:输入: s = "A man, a plan, ...
For the purpose of this problem, we define empty string as valid palindrome. 算法: AI检测代码解析 1. public boolean isDecent(char c) { 2. if (Character.isAlphabetic(c) || Character.isDigit(c)) { 3. return true; 4. else 5. return false; ...
代码(Python3) class Solution: def validPalindrome(self, s: str) -> bool: # 定义左指针 l ,初始化为 0 l: int = 0 # 定义右指针 r ,初始化为 s.length - 1 r: int = len(s) - 1 # 当还有字符需要比较时,继续处理 while l < r: # 如果 s[l] 和 s[r] 不相等,则需要删除字符 if...
