Answer 1

You probably did copy / paste this code from your IDE to the Sololearn playground.
I do not know why, but in that case, SL often recognizes empty fields as some (hidden) characters and report error. This is best seen in the web version of SL (like some dots).
You need to manually delete all empty fields in SL (with backspace) and format the lines of code again.

Here's your code, works perfect :

Answer 2

nice code.
but i don't know the correct reason why it is working.

Answer 3

because you are using loops to take input. This is not available on sololearn. But you can definitely run it on your pc.

Answer 4

Thanks alot , I also thought some thing like this, as when I retyped this code once again in Solo learn , it worked fine.
This problem also arises when I copy my codes typed in solo learn to hackerrank .
I also failed to complete a challenge in hackerank , because of this, as sololearn gives a better typing environment , I tried to type the code in solo learn and paste it in hackerrank.😑😑😞
Now I think , I have to use pc for hackerrank.
