Given input-output grid pairs as reference examples, carefully observe the patterns to predict the output grid for new test input. Each pair follows the same transformation rule. Grids are 2D arrays represented as strings, with cells (colors) separated by spaces and rows by newlines.
Here are the input and output grids for the reference examples:
Example 1
Input:
Black Yellow Black
Yellow Black Black
Yellow Black Yellow

Output:
Black Yellow Black
Yellow Black Black
Yellow Black Yellow
Yellow Black Yellow
Black Black Yellow
Black Yellow Black


Example 2
Input:
Green Green Black
Green Green Black
Green Green Black

Output:
Green Green Black
Green Green Black
Green Green Black
Black Green Green
Black Green Green
Black Green Green


Example 3
Input:
Black Green Green
Green Green Green
Green Black Green

Output:
Black Green Green
Green Green Green
Green Black Green
Green Black Green
Green Green Green
Green Green Black


Here is the input grid for the test example:
Input:
Black Black Gray
Gray Gray Gray
Black Black Black


Directly provide the output grids corresponding to the given test input grids, based on the patterns observed in the reference examples.
