write a C++ program

Given a string, you need to determine if it is a palindrome, considering only alphanumeric characters and ignoring cases. That is, you need to ignore all characters such as punctuation and spaces. Note: there is a function in C++ standard library called tolower which can be handy. Also you can use another C/C++ function isalnum. In general, try to use standard functions instead of reinventing the wheel.. You need to implement a function that takes a string as input and return true/false. Note: For the purpose of this problem, we define empty string as valid palindrome. For example, Input: A man, a plan, a canal: Panama Output: true Another example: Input: race a car Output: false Check out the starter code for the function signature.
