Enter both at the same time when the playground asks for your input like: 10 6

Made a few slight modifications to your code so it will loop until valid entry etc. https://code.sololearn.com/cQDlwTa1KQ1S/?ref=app

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 :)

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.

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.
