12.1. For 12.1a and 12.1b, list the neighbors for each polygon in Fig. 12.1 based on the specified contiguity type. You may want to create two lists like the ones below (one for Polygon Set #1 in 12.1a and one for Polygon Set #2 in 12.1b). (a) List the neighboring polygons (letter of the alphabet) for each polygon in Polygon Set #1 according to first-order rook contiguity. (b) List the neighboring polygons (letter of the alphabet) for each polygon in Polygon Set #2 according to first-order queen contiguity. 12.1A POLYGON SET #1 12.1B POLYGON SET #2 POLY NEIGHBORS POLY NEIGHBORS A A B B C C D D E E F F G G H H I I
