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.
Tests updated. If your solution still passes the "basic tests", post your solution here marked as a spoiler.
If you don't know that, start from the beginning, find a beginner Java tutorial, like this one, otherwise you'll not be able to solve any kata.
what's string methods and substring?? I've only heard of string
Most of the katas will test your knowledge, they won't tell you how to solve them. If you're doing Java try looking for string methods that allow you to get a substring. Either check Java docs or Google if you don't know where to start.
how do i do this??? I don't even know where to start from
For the c version of this kata I pass all assertions yet not the random test.
If I fail a case in the random test I should be able to see the input, whats expected and my output, like the assertions test.
Otherwise the kata is missing information.
