A palindrome is a word, phrase, number or other sequence of characters that is read backwards and forwards in the same way, ignoring spaces, punctuation and case-sensitivity. Your challenge is to write a C++ program that determines whether a string provided by the user is a palindrome or not. **Requirements**: * The program should ask the user to enter a string. * It should then check whether the string is a palindrome or not. * The program should ignore spaces, punctuation and case-sensitivity when checking whether the string is a palindrome. * After checking, the program should display a message indicating whether the string is a palindrome or not. **Example of execution**: ```cpp Type a string: Ana "The string is a palindrome." Type a string: Ame a ema "The string is a palindrome." Type a string: Programacao "The string is not a palindrome." ``` **Tip**: * You can scroll the string from left to right and from right to left simultaneously to check if the matching characters are the same. This is a simple c++ challenge that I want to see which of you will come up with the best answer, by creating a new post. don't forget to leave your comment or your **HANDSHACK** on the post
