EXAMPLE
a(6) = 37 - 29 = 8 because the partitions of 6 written in nondecreasing order are
.
. 6 = 6
. 3 - 3 = 0
. 2 - 4 = -2
. 2 - 2 + 2 = 2
. 1 - 5 = -4
. 1 - 2 + 3 = 2
. 1 - 1 + 4 = 4
. 1 - 1 + 2 - 2 = 0
. 1 - 1 + 1 - 3 = -2
. 1 - 1 + 1 - 1 + 2 = 2
. 1 - 1 + 1 - 1 + 1 - 1 = 0
----------------------------------
. 20 - 21 + 14 - 7 + 3 - 1 = 8
