Check Palindrome in Java Using Different Approaches| Java Interview QnA | Codefarm
In this video, we explore three different methods to check if a given string is a palindrome in Java. You'll learn about the
** two-pointer technique,
** reverse string comparison, and a
** recursive approach.
We'll also discuss which method is the most optimized in terms of time and space complexity. Whether you're preparing for coding interviews or just brushing up on your Java skills, this tutorial has got you covered!

Given a string, find the longest palindromic substring.
Given a string, check if any permutation of it is a palindrome.
Given a string, count how many palindromic substrings are present in it.
Given a string, find the minimum number of insertions needed to make the string a palindrome.
Write a method to check if two strings are anagrams of each other.
Given a string, find the length of the longest substring without repeating characters.
Check if one string is a rotation of another string.
Implement a method to perform basic string compression using the counts of repeated characters. For example, the string "aabcccccaaa" would become "a2b1c5a3".
Given an input string, reverse the string word by word.
Given an array of strings, group the anagrams together.
Given a string containing just the characters '(', ')', '{', '}', '[' and ']', determine if the input string is valid.
