Write a Python function that does the following: 1. Its name is reverse_string 2. It takes one string as argument 3. Using a while loop, it builds a new string that is the reverse of the original string 4. It returns the reversed string Write a Python function that does the following: 1. Its name is remove_spaces 2. It takes one string as argument 3. Using a while loop to create a string with no spaces 4. Return the news string with no spaces Write a Python function that does the following: 1. Its name is is_palindrome 2. It takes one string as argument 3. It checks whether the string is a palindrome. A Palindrome reads the same backward and forward. For example: madam, and nurses run 4. It returns True if the string is a palindrome, and False otherwise 5. Use your remove_spaces function to remove spaces from the argument before you check if the string is a palindrome 6. Use your reverse_string function to reverse the string and then compare the result to the original string
