# Write a function to gets a one to seven-digit integer,
# and adds together all of its digits.
# Then take the sum and do the following computation:
#    (((((sum + 9) * 2) - 4) / 2) - sum)
# note: the computation must be in this exact order
# For example, 1234567, the sum would be 28
#    (((((28 + 9) * 2) - 4) / 2) - sum)
# the result would be 7
#
# you may assume the incoming number does not contain lead zeros
