Do you know a mobile application (in addition to sololearn, of course 😄) to train algorithms. Like challenge codes?

Hi! I am better known for sites where they train and compete in writing the programs themselves in different programming languages. did you ask your question in search engines before that?

Answer 2

Yes, I have search it before 😄 .
I know sites too but it's less restrictive to train in a smartphone
