Shouldn't this be more like: ... where the absolute values of the differences of successive elements are included in the set of the absolute values of the numbers 1 through through n - 1? Otherwise sequences that have negative numbers in them will never match unless there is only one negative number and it is the last number in the sequence. Or is the problem to find the longest sequence of n > 0 where the absolute values of the differences of successive elements are included in the set of number 1 through n - 1; which also would suffer from the same negativity issue? Please clarify if I've missed something.
