Problem B:Longest Ordered Subsequence
A 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, e. g., (1, 7), (3, 4, 8) and many others. All longest ordered subsequences are of length 4, e. g., (1, 3, 5, 8).

this one is used to test arm7 str71x.
use a led to test GPIO.
a---------P0.0
b---------P0.1
c---------P0.2
d---------P0.3
e---------P0.4
f---------P0.5
g---------P0.6
just run it and you will see the led to show 0-9 all the time.
