# ordered integers?

## ordered integers?

What does the word 'ordered' integers mean? What order are we talking about?

Problem Description:
Write a threaded code to input an unknown number of sets of ordered integers...

my interpretation is that the "sets" are ordred, so they are really sequences.

Probably it tries to tell us that set 4 2 1 1 1 2 1 (4x7) and set 4 1 1 2 2 1 1 (7x4) are different.

I don't see that in the problem description. The rules just ask for "some tiling" and say nothing about the order in which the squares must be used....or am I missing something?

```The example demonstrates the meaning:
the output is all possible groupings of the same ordered sequence of numbers.
Permutations are not allowed, otherwise there would be more encodings in the output.
```

Thanks, I missed that. It makes it an easier problem, I think.
