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.
The requirement to give the output in a weirdly formatted string is ridiculous. I have one failed test where the answer only differs by trailing zeros... Basically my code works, but can't be validated:
Test Failed
Expected (max. 6 decimal places necessary): SOLUTION=(-6.000000; 6.500000; -2.875000)
But got: SOLUTION=(-6.0; 6.50; -2.8750)
So checked: SOLUTION=(-6.0; 6.50; -2.8750)
Really??
Test error when empty error. May be the test needs a correction.
It will work, but it's a very inefficient solution.
