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.
Me too, I don't get it either :(
Agreed. And I'll add that it would also aim to resemble the stated requirements so that the poor maintenance developer need not infer the relationship between the two.
I can see that but I don't understand how your algorithm work?
你是套用了啥公式呀?
Ignore the "even or odd" guide, start reading the number from the end, instead of the head, you will realise that it is always d, d2, d, d2, .... Whether the actual number has even numbers or not, doesn't matter.
I don't understand this approache. :(
