# define a function() that takes string input and return null if string is null and returns 1st occurrences of character followed by number of occurrences and so on. 

# This function takes a string and returns processed string output. 
def str_skimmer(input_string):
    # Return null string if input is null. 
    if not input_string:
        return ""
    # Store values for 2 parameters - "Reference Character and "Count"
    prev_char=input_string[0]
    op=[]
    count=1

    for i in input_string[1:]:
