The traditional palindrome problem is basically to find the length of longest symmetric substrings (palindromes) within a bigger string. It does so by creating an object of class Stack and calling its methods in some parts of your algorithm.I have been trying to solve the problem of circular palindrome all day, as part of a HackerRank challenge. The Palindrome class would be the ONLY one with the main() method which receives a command-line argument (JUST ONE STRING WITH NO WHITESPACES) and checks whether it's a palindrome or not. Second, develop a second Java class named Palindrome that in its main method, receives a string as a command-line argument, and then uses a Stack object to check whether the given string is a palindrome or not. Question: Develop a Stack class (NEEDS TO HAVE (at least) push, pop, and isEmpty methods) (The ONLY data structure you could use/have in your Stack class SHOULD be a CHAR ARRAY)
