Sequence Slicing

https://www.facebook.com/hackercup/problems.php?pid=317343604974808&round=154897681286317

Let S be a sequence of N natural numbers. We can define an infinite sequence MS in the
following way: MS[k] = S[k mod N] + N * floor(k / N). Where k is a zero based index.

For example if the sequence S is {2, 1, 3} then MS would be {2, 1, 3, 5, 4, 6, 8, 7, 9,
11, 10, 12...}
