Input value n is guaranteed to be correct (n>0).

because that's just saying it twice while only making it more confusing (does it mean something more than that?) - should it be stating an upper bound as well? I think it should but I haven't bothered to understand the essence of the task - maybe the upper bound turns out irrelevant.

and if correct means something other than n>0 then it should say that instead -

Who wants a Python translation?

Fixed some issues in random tests and added JS translation.

This has been added some time ago

I even wrote comments in both Chinese and English for my code...

only 1 line? dude...

can someone explain the regex in the the pattern?

Wow! I've been racking my head for 3 hours on how to build logic, and here is a solution in 1 line! That's what ignorance of the basics of programming and language means.

Is this case sensitive? Would this return false if str ends with ending but ending was input in a different case than it appears in str?

😄

If someone just add 10 more words, this doesn't seem very scalable.

Can you be a bit more specific in the description about what datatype the column "number" should be?

The first time I actually submitted the top solution by myself... feels good.
