Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Thanks, actually i am new here. So i didn't exactly know how this works. and btw i solved the kata.
Not an issue. If you want somebody to help you, post your code with a spoiler tag, or try solving the kata without using regex.
I don't know what's happening here, i'm using two regexs, separately for both 4 digit and 6 digit PIN. But the validPin testcase is not working. I am new here, and i am new in coding field. So need your help guys.
