Description: Problem B: Longest Ordered SubsequenceA numeric sequence of ai is ordered if a1 <a2 <... <aN. Let the subsequence of the given numeric sequence (a1, a2, ..., aN) be any sequence (ai1, ai2, ..., aiK), where 1 <= i1 <i2 <... <iK <= N. For example, sequence (1, 7, 3, 5, 9, 4, 8) has ordered subsequences, eg, ( 1, 7), (3, 4, 8) and many others. All longest ordered subsequences are of length 4, eg, (1, 3, 5, 8).
