Answer 17

You are having input problems
You have to give all your inputs at once like :
9
6 and enter
Sololearn playground works like this only :)

Answer 18

Yup the solution to the problem by Daljeet Singh and
ChaoticDawg is right.
You just need to enter both the values at the same time either with a space or an enter. Then you can press submit to get the correct output.

Answer 19

Prathik Shetty you aren't looping over that part of your code. If that's what you want to do then you'd need to wrap your code in a loop that exits the loop when a valid entry is made.
