I: Given a string s, partition s such that every substring of the partition is a palindrome. Return all possible palindrome partitioning of s. For example, given s ="aab",Return [ ["aa","b"], ["a","a",&quo…
131. Palindrome Partitioning Given a string s, partition s such that every substring of the partition is a palindrome. Return all possible palindrome partitioning of s. For example, given s = "aab",Return [ ["aa","b"], ["…
Given a string s, partition s such that every substring of the partition is a palindrome. Return the minimum cuts needed for a palindrome partitioning of s. For example, given s ="aab",Return1since the palindrome partitioning["aa",&quo…
Given a string s, return all the palindromic permutations (without duplicates) of it. Return an empty list if no palindromic permutation could be form. For example: Given s = "aabb", return ["abba", "baab"]. Given s = "a…

Palindrome Time Limit:15000MS Memory Limit:65536KB 64bit IO Format:%I64d & %I64u Submit Status Description Andy the smart computer science student was attending an algorithms class when the professor asked the students a simple question, &quo…
Given an integer n, find the closest integer (not including itself), which is a palindrome. The 'closest' is defined as absolute difference minimized between two integers. Example 1: Input: "123" Output: "121" Note: The input n is a po…
Given a string s, partition s such that every substring of the partition is a palindrome. Return all possible palindrome partitioning of s. Example Given s = "aab", return: [ ["aa","b"], ["a","a","b&q…
Given a singly linked list, determine if it is a palindrome. Follow up:Could you do it in O(n) time and O(1) space? 判断一个链表是否为回文链表,有很多方法都可以进行判断,可以先遍历链表然后将值全部存储到vector之中,也可以遍历链表然后将list中的值都压倒堆栈中再和List进行比较, 但是想要达到题目上面的 时间复杂度为O(n),而空间复杂度为O(1)还要用到递归: 首先是不用…
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 lengt…
Given a singly linked list, determine if it is a palindrome. Follow up:Could you do it in O(n) time and O(1) space? 题目标签:Linked List 题目给了我们一个 linked list,让我们判断它是不是回文. 这里可以利用 #206 Reverse Linked List 把右边一半的链表 倒转,然后从左右两头开始比较链表是否是回文. 这样的话,首先要找到链表的中间点,然后…
翻译 给定一个单链表,确定它是否是回文的. 跟进: 你能够在O(n)时间和O(1)空间下完毕它吗? 原文 Given a singly linked list, determine if it is a palindrome. Follow up: Could you do it in O(n) time and O(1) space? 进阶 bool judge(ListNode *head, ListNode* &cur) { if (!head) return true; if (!jud…
Level: Easy 题目描述: Given a singly linked list, determine if it is a palindrome. Example 1: Input: 1->2 Output: false Example 2: Input: 1->2->2->1 Output: true Follow up: Could you do it in O(n) time and O(1) space? 思路分析: 由题意知,我们要判断一个链表是不是…
题目描述 Determine whether an integer is a palindrome. An integer is a palindrome when it reads the same backward as forward. Example 1: Input: 121 Output: true Example 2: Input: -121 Output: false Explanation: From left to right, it reads -121. From rig…
