409. Longest Palindrome 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 iscasesensitive,forexample "Aa"is no
[LeetCode] Longest Palindrome Given an integer array, find three numbers whose product is maximum and output the maximum product. Example 1: Input: [1,2,3] Output: 6 Example 2: Input: [1,2,3,4] Output: 24 Note: The length of the given array will be in range [3,104] and all e...

To find the longest palindromic substring, we need to expand around each Tisuch that Ti-d… Ti+dforms a palindrome. You should immediately see that d is the length of the palindrome itself centered at Ti. We store intermediate result in an array P, where P[ i ] equals to the length ...

409. Longest Palindrome 题目 思路 使用Counter 对数据进行计数,添加1个奇数 对其他的奇数-1处理,求和,即可。 我的总体思路是没有问题的,但代码细节没处理好,效率极低。 我的代码(效率极低) 优秀代码 代码1: 同样使用词典,计算每一个字符出现的个数。对于偶数,直接增加,对于奇数添加n-1,并做标记。 根据标记...
Idea is similar to shortest palindrome, we need to create a trie that reflects the reverse of all words. We match head and tail first, the rest of string/substring should be a palindrome. publicclassSolution {classTrieNode { TrieNode[] children=newTrieNode[26];intwordArrayIndex = -1;//...
We store intermediate result in an array P, where P[ i ] equals to the length of the palindrome centers at Ti. The longest palindromic substring would then be the maximum element in P. Using the above example, we populate P as below (from left to right): ...
Given an unsorted array of integers, find the length of the longest consecutive elements sequence. For example, Given [100, 4, 200, 1, 3, 2], The longest consecutive elements sequence is [1, 2, 3, 4]. Return its length: 4.
