A call to the function might look like this, taking in a string of words and then returning the string of string words. You should ignore the case of the words when sorting them. However, the output should have the same upper and lowercase letters as the corresponding input words. For example, the input string 'banana ORANGE apple' should produce the output shown here with 'apple banana ORANGE.'
