Have you consider that the string might be empty? This is a good question to ask during an interview. For the purpose of this problem, we define empty string as valid palindrome. 处理好大小写转换、非法字符忽略就可以。 1classSolution {2public:34boolisPalindrome(strings) {5if(s.empty())ret...

Have you consider that the string might be empty? This is a good question to ask during an interview. For the purpose of this problem, we define empty string as valid palindrome. 判断回文是否有效。 思路:首先先将给定字符串中字母和数字挑选出来,并将大写字母统一改写成小写字母 ...
for(i=0;i<=len;i++) { dp[i][0]=0; dp[0][i]=0; } for(int i=1;i<=len;i++) for(int j=1;j<=len;j++) { if(str1[i-1] == str2[j-1]) dp[i][j]=dp[i-1][j-1]+1; else if(dp[i][j-1] >= dp[i-1][j]) ...
A palindrome is a string that reads the same backward as forward, for example strings "z", "aaa", "aba", "abccba" are palindromes, but strings "codeforces", "reality", "ab" are not. Input The first and single line contains strings(1 ≤ |s| ≤ 15). ...
for (int i = 0; i < n; i++) { for (int j = i; j < n; j++) { if (substr_table[i][j] > max_len) { max_len = substr_table[i][j]; } } } return max_len; // Return the length of the longest palindrome } // Main function int main() { // Test cases string ...

树中的回文个数(Pseudo-Palindromic Paths in a Binary Tree)0 赞同 · 0 评论文章 二. 思路 for循环+递归。 让每个字符串都有机会成为一个回文子字符串的起始字符,任意长度挨个成为回文子字符串的长度。 代码: class Solution { public List<List<String>> partition(String s) { List<List<String>> res ...
