You have a string of words and digits divided by comma. Write a program which separates words with digits. You shouldn't change the order elements.
Your program should accept as its first argument a path to a filename. Input example is the following
8,33,21,0,16,50,37,0,melon,7,apricot,peach,pineapple,17,21 24,13,14,43,41
melon,apricot,peach,pineapple|8,33,21,0,16,50,37,0,7,17,21 24,13,14,43,41
As you cas see you need to output the same input string if it has words only or digits only.
