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.
Try running with Kotlin 1.3. It worked for me
While testing my code with random tests, I encountered an error:
src/test/kotlin/tests.kt:8:16: warning: 'toLowerCase(): String' is deprecated. Use lowercase() instead.
val _x = x.toLowerCase().replace(Regex("[^aby]"), "");
^
even through my code use alreadt lowercase()
However, I am already using lowercase() function in my code (... x.lowercase()...). Has anyone else encountered a similar issue or am I missing something?
