Hello Siddharth, a small error was there, if it is not possible you are outputting “No window” but we need to output “No String”.
Just make it correct it will work fine.
I hope it is clear to you. In case it is clear to you pls mark it as resolve and provide the rating as well as feedback so that we can improve ourselves.
In case there is still some confusion pls let me know, I will surely try to help you out.
Thanks :slight_smile:
Happy Coding !!
