Question

A palindrome is a word or phrase that reads the same forwards and backwards, character for character,disregarding punctuation, case or spaces. Some examples are "racecar", "madam,I'm Adam".Write a program that allows the user to input a word or phrase and then determines if it is a palindrome.The program should use a Boolean Function procedure named Palindrome that returns the value True when the word or phrase is a palindrome and the value False otherwise
