"""
Write a function count_cm that takes one parameter, a string of characters, 
and returns the number of characters between c and m and the number of characters between C and M. 
Pay attention: THE FUNCTION RETURNS TWO COUNTERS.

For example, if the string is CatDogcAlm the function returns: 4,2

Write a program that reads 5 strings, and for each string prints 
the number of chars between 'c' and 'm' (inclusive), 
and the number of chars between 'C' and 'M' (inclusive). 
In addition, the program finds the average number of chars in each category.
