Check if Palindrome
Write a method that checks if a string is a palindrome (reads the same forwards and backwards). The method should ignore case and spaces when determining if a string is a palindrome. Return false for null or empty strings.
A palindrome is a word, phrase, or sequence that reads the same backward as forward. For example, "racecar" is a palindrome, and "A man a plan a canal Panama" is also a palindrome when ignoring spaces and case.
Method Signature
public static Boolean isPalindrome(String text)
Examples:
Input: text = "racecar"
Output: true
Explanation: "racecar" reads the same forwards and backwards
Input: text = "A man a plan a canal Panama"
Output: true
Explanation: Ignoring spaces and case, this reads the same forwards and backwards
Input: text = "hello"
Output: false
Explanation: "hello" reversed is "olleh", which is not the same
Input: text = null
Output: false
Explanation: Null strings are not considered palindromes
Input: text = ""
Output: false
Explanation: Empty strings are not considered palindromes
Input: text = "Racecar"
Output: true
Explanation: Case is ignored, so this is a palindrome
