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
