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:
Gray Gray Gray Black Gray
Black Black Gray Black Gray
Gray Black Yellow Black Gray
Gray Gray Gray Gray Black
Black Gray Gray Gray Black

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


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

Black Green Green Black Green


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

Output:
Black Black Black Green Green
