Detailed Description

Use the SlicerMap to compute the sum of odd and even numbers separately.

Graphically, this can be represented as:

The expected output of this program is:

{1=1.0}
{1=1.0, 6=1.0}
{1=1.0, 4=1.0, 6=1.0}
{1=1.0, 3=1.0, 4=1.0, 6=1.0}
{1=1.0, 2=1.0, 3=1.0, 4=1.0, 6=1.0}
{1=2.0, 2=1.0, 3=1.0, 4=1.0, 6=1.0}
{1=2.0, 2=1.0, 3=1.0, 4=1.0, 6=1.0, 9=1.0}
