Hackerrank code challenges

Hey guys,

I was taking a look into the some of the challenges subdirectories in the directory training/code/hackerrank. All the challenges subdirs I checked do only have OTHERS.lst and LINK.lst. Then, is hackerrank a special case for submitting structure?
If that is the case, how do you know which is my submision on hackerrank itself?

Hackerrank is no different from other challenges sites, if you find a folder with only LINK.lst and OTHERS.lst that means no one has solved this challenge yet. These are the challenges you should aim for, once solved and merged, they become unique solutions.

If that is the case, how do you know which is my submision on hackerrank itself?

Sorry I don’t understand this question, what do you mean by submission on hackerrank

Well, the first paragraph answers me well. Thanks!
