Are people seriously writing all these neat programs on their phone?

Question

I am referring to the ones featured on this app. I am new to this app and was wondering how people would write such long programs on their phones.

Answer 1

There is also the sololearn webpage, where you can connect your account and do courses also. They features everything but challanges. So... its posible? yes. But nothing like a good PC.

Answer 2

not necessarily you can write the code on your desktop and copy it to sololearn. if you know how to organize your code then yes you can.

Answer 3

This makes more sense. I was trying to type a simple program and it was taking forever. Thank you so much for your response
