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!
Stick to int.
Ok, i just got confused with the wording, thank you for explaining.
D is the number of dimensions, N is the length on each dimension.
=> D=2, N=3 means a "2D squared array" 3x3. No contradiction with the description, afaik.
I don't undestand what D and N means, because the example is very confusing, so if N is the length of each item of the array and D is the length the array, D=2, N=3 results in a array of 2 lengths, with each item being an array of 3 elements, but the example shows an array of 3 elements by 3 elements, which contradicts the paragraphs before.
The description is very confusing for anyone that is not native speaker, please make it clear what I need to do to complete this kata. Thanks.
Nice kata. On the large Python tests my code output experiences precision error (1E-12 or so) on here but is arbitrarily precise when I run on my personal machine (python 3.7.3). Anyone have a suggestion?
