#write a function letter_found
#that has two parameters - list of characters and additional character
#the function counts the number of times additional character appears in the list
#and creates a new list of all indexes character appear in the list
#function returns the list of indexes and the number of appearances
#assume that all letters are upper case letters
#complete the main program
