@admin why does the same code show WA and AC for two different users?!
may be test cases were updated between @anon11076894 submission and your submission, and for single digit numbers (len(l)==1) both first and last digits are same, so answer should be 2*number.

exactly, that’s what I thought.
but this is not possible, because I had submitted the code (with condition of len(string) == 1 once before him also, and it gave me WA. Also, our recent submission was not very far apart, and since this is a fairly old problem of practice beginner, i hardly think they’ll be changing anything rn
He submitted in 2019, and you in 2020, but this questions has submissions from 2015, so i also don’t think that they would have changed anything after 4 years.
