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.

Ah, shifting before masking allows you to keep the mask at 0xFF. Lovely. I like how you use an array collection as well.

O(n^2)
only happens when you have nested loops. Since the two loops are not nested at all (they're sequential), it'sO(n)

I think it doesn't make it
n^2
. It is still linear -2n
, if you want. But constants are usually discarded in Big O, so justn
.n^2
would be if, for example, for every element of that array there were another array which would be iterated.No, it's
O(n)
.Is it O(n^2) solution?
