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.
That is not at all clever nor best practice as he added true:false in the end that does absolutely nothing lmao.
Not so efficient to compute .sqrt(n) twice (instead of saving it in a variable first)
Yes, you' re right!
Actually i thought about that after i submitted my code :)
The ternary is unnecessary here, "return Math.sqrt(n) == (int)Math.sqrt(n);" alone would do the exact same.
some test cases when i try to sumbit are faulty!
