Answer 1

the problem is just because SoloLearn codes are compiled online and so user input are not taking on runtime, so you need to input all values then it compile and bring the result down to you, if SoloLearn include offline compiler into the app, it will be damn too heavy, even you will hate to use a very slow app

Answer 2

Dear @Carmine Pietroluongo I understand you but the compilers works behind must have some limitations for security concerns.Cause compilers can crash or disturb running systems. The compilers are for basic requests ; it is always best to have your test platform at your own system.

I hope this helps.
