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 length of given string will not exceed 1,010. Examp...
Letters arecase sensitive, for example,"Aa"is not considered a palindrome. Example 1: Input:s = "abccccdd"Output:7Explanation:One longest palindrome that can be built is "dccaccd", whose length is 7. Example 2: Input:s = "a"Output:1Explanation:The longest palindrome that can be built ...
将s变为字符数组,如果当前字符表示的十进制数,在数组中对应的元素为0就自加1,否则就自减1,然后count加2,最后再去判断数组中的元素有没有大于0的存在,如果存在即表示有字符出现了奇数次,然后count需要加1,且只用加一次。 publicintlongestPalindrome5(String s){int[] arr =newint[58];intcount =0;for(char...
public int longestPalindrome(String s) { Map<Character, Integer> map = new HashMap<>(); for (char c : s.toCharArray()) { map.put(c, map.getOrDefault(c, 0) + 1); } boolean odd = false; int ans = 0; for (Integer count : map.values()) { ...
