# This code snippet takes a string input and append suffixes based on a number of conditions
# Condtion:
#    1 if the lenght of the string is grater than 3 characters and is not already
#       ended with "ing" then add suffix "ing"
#    2 else if the lenght of the string is grater than 3 then add suffix "ly"

# The code snippet can be improved to include more business conditions.
