} the above method of writing is enforceable. What I want to ask is whether it is advisable to write in this way. Does it need to be optimized?
personally, I feel that this kind of auxiliary variable is very awkward to be written in data. Obsessive-compulsive disorder is fast
, but the disadvantage is that I can"t use this--. I don"t know how to use
. Thank you
