Function Signature

bool isPalindrome(const std::string& str);

Input

A string str (1 <= str.length() <= 10^5) consisting of alphanumeric characters, punctuation and spaces.

Output

true if str is a palindrome, false otherwise.

Example

bool result1 = isPalindrome("A man a plan a canal Panama"); // true

bool result2 = isPalindrome("race car"); //

true bool result3 = isPalindrome("hello world"); // false

Convert the input string to lowercase to ignore capitalization.
Remove spaces and punctuation from the string to focus only on alphanumeric characters.
Use a stack to push characters onto it as you iterate through the string.
Use a queue to enqueue characters as you iterate through the string in reverse.
Compare characters popped from the stack with characters dequeued from the queue to check if they match.
Use the C++ Standard Library's std::stack and std::queue for this exercise.

Constraints

Do not use additional data structures or containers beyond the stack and queue for this exercise.
