回文正序和逆序一样的字符串,例如abccba 方法一 def is_palindrome1(text): l = list(text) l.reverse() t1 = ''.join(l) if t1 == text: print 'the text is palindrome' else: print 'the text is not palindrome' 方法二 def is_palindrome2(text): t1 = text[::-1] if t1 == text: print
Question: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.(给定一个字符串S,在S中找到最长的回文子字符串,假定最长的回文字符串长度是1000,并且在这个字符串中存在唯一的一个最长回文子字符串

回文字符串:字符串从前往后读和从后往前读字符顺序是一致的. 判断一个字符串是不是回文字符串 function isPalindrome(str) { var str1 = str.split('').reverse().join(''); return str1===str; } 判断字符串中的所有回文字符串 function palindromeStr(str) { var temp = ''; var result=[]; for(var i=0;i<str.length;i++){ tem
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
Given a non-empty string s, you may delete at most one character. Judge whether you can make it a palindrome. Example 1: Input: "aba" Output: True Example 2: Input: "abca" Output: True Explanation: You could delete the character 'c'.
