Define A as a sequence of 1 and 2 where:
A(1) = 1 and
A(n) minimizes the length of the longest possible doubled suffix of A(1..n).

For example, the next element of the sequence 1,2,1,1,2,2,1,2 would be a 1, which creates the longest doubled suffix of "(2,1),(2,1)", whereas putting a 2 instead would create a longer doubled suffix of "(1,2,2),(1,2,2)".

Output the first 1,000 elements of A.
