Note that indexing starts from 0. OP solved it though, closing.

just return true statements.

i <= 9 - why 9?
My guess is this is causing inifinite loop.

Try printing value of n at the begining of while loop.

OP solved the kata

bored?

great but you dont need ternary if youre after short line, just return the statement

sorry officer hobovsky, i should've put my question in questions, please dont arrest me

@DeCaTou: you can print the input to console to see which test is failing. In your case it is n = 500000000000.

"My solution does not work" is not a valid kata issue. If you want to raise an issue, you have to tell what is wrong with the kata.
