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.
Not really... both a shallow and deep copy occupy different memory addresses. The difference has to do with what's in the copy. A deep copy of an array is a copy of the array and a copy of the items in the array. A shallow copy is a copy of the array, but not a copy of the items. The difference is easier to see if you had an array of mutable objects, like an array of dicts. For example,
If you add a new item in
x
, it will not be iny
.But if you modify x[0], you will also modify y[0].

What's the difference between mutating the list VS changing the list?
I thought it's the same thing...

Does this mean: this solution did not satisfy all conditions of the question? It says in description: "Do not mutate the original array/list". This solution changed the original list, hence, it's a "wrong" solution.
It is a shallow copy.
