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, the plot thickens.
I can get this to pass all the tests, when I put 4I in I get the expected 4I1 but on attempting it I get the following error with similar tests:
java.lang.NumberFormatException: For input string: "6c"
at java.base/java.lang.NumberFormatException.forInputString(NumberFormatException.java:67)
The above passes the test phase when I manually put 6c in and I get no errors on my IDE.
Can someone tell me what the answer to passing ("4I") should be please?
I thought it should be 4I1 but it is giving an error on that answer with out of bounds (despite working on my IDE) making me think I have got the answer wrong.
