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. Didn't consider that applied to the string after processing.
I'm a little confused by the Kata Description statement, "You can see that they are case insensitive and disregards non alphanumeric characters." That implies to me that for this exercise, special characters are not to be considered when evaluating the string.
One of the tests reported that "##" should return true. While I agree ## is a valid palidrome, if special characters are ignored the string is empty and is not a palidrome.
Thank you! I didn't know that.
Yes! That's a great idea, thank you @matthewglover
Thanks @matt c and @matthewglover I appreciate your hint.
I should have specified that I'm trying to train in Ruby. Isn't everyone using Ruby? :)
And just an fyi, I'm a her, not a him.

Ack! Thank you taw. I should have caught that.
Working on this in Ruby and wonder why newline is not considered whitespace but tab is?
(not a spoiler, these tests are from the example text cases)
Test.assert_equals "w\n".whitespace?, false
Test.assert_equals "\t".whitespace?, true
