this is a program that checks to see if a sentence can be a palindrome or not. ( Palindrome happens when a word or a sentence is the same when you read it from left to right or right to left). This is the code that I have so far and it works fine. it removes the symbols and number and convert all letters to capital letter. I need help implementing it into a while loop so user can enter as many sentences they want and the press q to quit!
