Below image shows the output of the above longest palindrome java program. We can improve the above code by moving the palindrome and longest lengths check into a different function. However, I have left that part for you. :) Please let me know if there are any other better implementations ...
A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward as forward, such as madam. Write a java program to find the longest palindrome present in a given string. For example, in the string a
for(inti=0;i<n-1;++i) { searchPalindrome(s,i,i,start,maxLen); searchPalindrome(s,i,i+1,start,maxLen); } returns.substr(start,maxLen); } voidsearchPalindrome(strings,intleft,intright,int&start,int&maxLen) { while(left>=0&&right<s.size()&&s[left]==s[right]) { --left;++rig...
Approach #2: Java. class Solution { public int longestPalindrome(String s) { int[] count = new int[128]; for (char c : s.toCharArray()) count[c]++; int ans = 0; for (int v : count) { ans += v / 2 * 2; if (ans % 2 == 0 && v % 2 == 1) ans++; } return ans...

2 本体可以使用动态规划去解答,但是我用了之后没能AC,也可以使用从中间向两边延伸去查找最长回文子串。先提供第二种方式的解答,通过提交public class Solution {public String longestPalindrome(String s) { int max = Integer.MIN_VALUE;//最长回文子串长度; String result = ""; for(int i=0;i<...
httphttpsjava网站网络安全 A palindrome is a string that reads the same from the left as it does from the right. For example, I, GAG and MADAM are palindromes, but ADAM is not. Here, we consider also the empty string as a palindrome. ...
