# Every condition is layed out explicitly to make the code readable
# It's a good first candidate because it makes testing simple

end

# Even though there's no increase in complexity this version is slightly faster
# It checks if we can just print the number and goes on to the next
# If it can't just print the number, then it concatenates whicever strings match the individual checks
# Either for being a multiple of 3 or a multiple of 5
# We can leverage any unit tests written for the problem above
