Given an integer x, return true if x is a palindrome and false otherwise. Example 1: Input: x = 121 Output: true Explanation: 121 reads as 121 from left to right and from right to left. Example 2: Input: x = -121 Output: false Explanation: From lef...
Problem Statement Given the head of a singly linked list, return true if it is a palindrome or falseotherwise. (link) Example 1: Input: head = [1,2,2,1] Output: true Example 2: Input: head = [1,2] Output: false Constraints: The number of nodes i...
Are you interested in learning about palindromes? Perhaps you're working on a project that requires you to check if a given string is a palindrome. In this blog post, we'll explore how to create a simple JavaScript function to do just that. What are ...

Given a string s, partition s such that every substringof the partition is a palindrome. Return all possible palindrome partitioning of s. LeetCode Problem - 131 class Solution { // Method to partition the input string into all possible palindrom...
class Solution: def partition(self, s: str) -> List[List[str]]: def checkPalindrome(word): return word == word[::-1] ans = [] def backtrack(index, prev, temp): nonlocal ans if index >= ...
Given an integer array queries and a positive integer intLength, return an array answer where answer[i] is either the queries[i]<sup>th</sup> smallest positive palindrome of length intLength or -1 if no such palindrome exists. A palindrome is a numbe...
In the realm of programming, algorithms serve as the backbone of problem-solving methodologies, offering structured steps to tackle computational tasks efficiently. It's important to form efficient algorithms that optimize problem-solving processes. ...
