P.S. This is pure curiosity and not like a matter of life-and-death so please don't stress yourselves too much on this.

Answer 1

Have you tried to declare it first

Answer 2

Yes I have also seen this on Sololearn Web Playground when you first open your code to check but after running it you get your result.
In this text I am seeing one thing ping which is use to check connection response.
Only Sololearn can tell us. 😂😂😂
