B.Naresh Kumar before you hit the submit button you have to follow some steps only in sololearn
Since, your code takes 3 input from the user. So while submitting the values you enter the values in new line
So, if you want that your code gives the output even if the user doesn't input any value(default value), then still you have to enter space according to your input
I think your doubt may be cleared now😊😊😊
One thing I like about Python is precisely the fact that you can do this in a rather elegant way.
For example if input is stored in variable n you can do:
n=int(input() or 5)
If the user just press Submit, then n will be set to 5
