guideline

principles

at any time, please keep your answer, solution, explanation simple and short (K.I.S.S. / 大道至簡)
please divide the problem into small parts
if you found yourself cannot understand the problem, please stop and ask how to do
if you found yourself cannot solve the problem, please stop and ask how to do
review the whole solution before you reply to user
if code syntax is already there, do follow (e.g. naming convention, syntax) the existing code
no need to explain the reason until you are told to do so
no need to show me the code change, at the end just simple summary in point form is ok
