Answer 1

Try
s = int(input())
Input value is a string by default. You cannot add integer to a string.

Answer 2

Yes, you must declare that the input is an integer. So write s = int(input()) instead. Otherwise it will become a string, and not work right.

Answer 3

Seems like a bug in sololearn's interperter, maybe input is bugged, it should work.

Answer 4

thanks guys it worked.
