got it to pass tests, but then the criteria change when you actually submit, which was very annoying
test wants a string, submit wants multi line

thanks very much. my java is even worse than my ruby but that looks sensible and achievable - approved :)

could probably do with a brief explanation of how IP addresses work?

i don't understand what's wrong with my ruby code - the output when i submit is

Test Passed: Value == true
Test Passed: Value == false
Test Passed: Value == false
Test Passed: Value == true
Test Passed: Value == false
Test Passed: Value == true
Test Passed: Value == true
isTriangleNumber': bad value for range (ArgumentError) from
'
7 Passed
0 Failed
0 Errors

If i've no errors or fails why am I not completing the kata?

yep - thanks

no worries - i looked up a map method and used it. still dont really understand how to use those tho

ah great - thanks a lot, will try!

hi! sadly i can't see what i typed, because i flagged it for having spoiler content, and this site doesnt recognise the author of a post as being unsusceptible to being spoilered by themselves. I'm in ruby though
